MFC r355936, r356045: remove unused kbd drivers
r355936:
Kill off dummy kbd drivers
As far as I can tell, these are an artifact of times when linker sets
couldn't be empty, otherwise the kernel build would fail due to unresolved
symbols. hselasky fixed this in r268138, and I've audited the kbd portions
to make sure nothing would blow up due to the empty linker set and
successfully compiled+ran a kernel with no keyboard support at all.
Kill them off now since they're no longer required.
r356045:
terasic_mtl: kill off final dummy keyboard driver
The rest were removed in r355936, which speculated that the cause of this
phenomenon was due to an inability to have an empty linker set. The comment
included with this one shows that this was, in fact, not the reason.
Regardless, syscons no longer seems to have an issue with not having any
keyboard drivers and in-fact ignores the keyboard probe anyways. |

MFC: r342634 (partial)
o Don't allocate resources for SDMA in sdhci(4) if the controller or the
front-end doesn't support SDMA or the latter implements a platform-
specific transfer method instead. While at it, factor out allocation
and freeing of SDMA resources to sdhci_dma_{alloc,free}() in order to
keep the code more readable when adding support for ADMA variants.
o Base the size of the SDMA bounce buffer on MAXPHYS up to the maximum
of 512 KiB instead of using a fixed 4-KiB-buffer. With the default
MAXPHYS of 128 KiB and depending on the controller and medium, this
reduces the number of SDHCI interrupts by a factor of ~16 to ~32 on
sequential reads while an increase of throughput of up to ~84 % was
seen.
Front-ends for broken controllers that only support an SDMA buffer
boundary of a specific size may set SDHCI_QUIRK_BROKEN_SDMA_BOUNDARY
and supply a size via struct sdhci_slot. According to Linux, only -
unsupported in stable/11 anyway - Qualcomm MSM-type SDHCI controllers
are affected by this, though.
Requested by: Shreyank Amartya (unconditional bump to 512 KiB)
o Introduce a SDHCI_DEPEND macro for specifying the dependency of the
front-end modules on the sdhci(4) one and bump the module version
of sdhci(4) to 2 via an also newly introduced SDHCI_VERSION in order
to ensure that all components are in sync WRT struct sdhci_slot.
o In sdhci(4):
- Make pointers const were applicable, and
- replace a few device_printf(9) calls with slot_printf() for
consistency. |

MFC r327367:
Make kernel option KERNVIRTADDR optional, remove it from std.<platform>
files that can use the default value.
It used to be required that the low-order bits of KERNVIRTADDR matched
the low-order bits of the physical load address for all arm platforms.
That hasn't been a requirement for armv6 platforms since FreeBSD 10.
There is no longer any relationship between load addr and KERNVIRTADDR
except that both must be aligned to a 2 MiB boundary.
This change makes the default KERNVIRTADDR value 0xc0000000, and removes the
options from all the platforms that can use the default value. The default
is now defined in vmparam.h, and that file is now included in a few new
places that reference KERNVIRTADDR, since it may not come in via the
forced-include of opt_global.h on the compile command line. |

r323474:
Add a default implementation that returns ENODEV for start, repeat_start,
stop, read, and write methods. Some controllers don't implement these
individual operations and have only a transfer method. In that case, we
should return an indication that the device is present but doesn't support
the method, as opposed to the kobj default error ENXIO which makes it
look like the whole device is missing. Userland tools such as i2c(8) can
use the differing return values to switch between the two different i2c
IO mechanisms.

Defer attaching and probing iicbus and its children until interrupts are

not using config_intrhook to defer attachment. That has led, over the

o Fix some overly long lines, whitespace and other bugs according to
style(9) as well as spelling etc. in mmc(4), mmcsd(4) and sdhci(4).
o In the mmc(4) bridges and sdhci(4) (bus) front-ends:
- Remove redundant assignments of the default bus_generic_print_child
device method,
- use DEVMETHOD_END,
- use NULL instead of 0 for pointers.
o Trim/adjust includes.
o Add and use a MMC_DECLARE_BRIDGE macro for declaring mmc(4) bridges
as kernel drivers and their dependency onto mmc(4).
o Add support for eMMC "partitions". Besides the user data area, i. e.
the default partition, eMMC v4.41 and later devices can additionally
provide up to:
1 enhanced user data area partition
2 boot partitions
1 RPMB (Replay Protected Memory Block) partition
4 general purpose partitions (optionally with a enhanced or extended
attribute)
Besides simply subdividing eMMC devices, some Intel NUCs having UEFI
code in the boot partitions etc., another use case for the partition
support is the activation of pseudo-SLC mode, which manufacturers of
eMMC chips typically associate with the enhanced user data area and/
or the enhanced attribute of general purpose partitions.
CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation.
o Now that properly issuing CMD6 is crucial (so data isn't written to
the wrong partition for example), make a step into the direction of
correctly handling the timeout for these commands in the MMC layer.
Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as
recommended by relevant specifications.
o Add an IOCTL interface to mmcsd(4); this is sufficiently compatible
with Linux so that the GNU mmc-utils can be ported to and used with
FreeBSD (note that due to the remaining deficiencies outlined above
SANITIZE operations issued by/with `mmc` currently most likely will
fail). These latter have been added to ports as sysutils/mmc-utils.
Among others, the `mmc` tool of mmc-utils allows for partitioning
eMMC devices (tested working).
o For devices following the eMMC specification v4.41 or later, year 0
is 2013 rather than 1997; so correct this for assembling the device
ID string properly.
o Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at
least for some of the above a matching pair is required.
o In the ACPI front-end of sdhci(4) describe the Intel eMMC and SDXC
controllers as such in order to match the PCI one.
Additionally, in the entry for the 80860F14 SDXC controller remove
the eMMC-only SDHCI_QUIRK_INTEL_POWER_UP_RESET. |

This is only a workaround as in fact fact this hardware is capable of detect
the USB port mode based on type of cable and act according with the detected

INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.
There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.
While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

Remove FDT specific parts from INTRNG. Change its interface to make it
universal.
(1) New struct intr_map_data is defined as a container for arbitrary
description of an interrupt used by a device. Typically, an interrupt
number and configuration relevant to an interrupt controller is encoded
in such description. However, any additional information may be encoded
too like a set of cpus on which an interrupt should be enabled or vendor
specific data needed for setup of an interrupt in controller. The struct
intr_map_data itself is meant to be opaque for INTRNG.
(2) An intr_map_irq() function is created which takes an interrupt
controller identification and struct intr_map_data as arguments and
returns global interrupt number which identifies an interrupt.
(3) A set of functions to be used by bus drivers is created as well as
a corresponding set of methods for interrupt controller drivers. These
sets take both struct resource and struct intr_map_data as one of the
arguments. There is a goal to keep struct intr_map_data in struct
resource, however, this way a final solution is not limited to that.
(4) Other small changes are done to reflect new situation.
This is only first step aiming to create stable interface for interrupt
controller drivers. Thus, some temporary solution is taken. Interrupt
descriptions for devices are stored in INTRNG and two specific mapping
function are created to be temporary used by bus drivers. That's why
the struct intr_map_data is not opaque for INTRNG now. This temporary
solution will be replaced by final one in next step.

so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc

Add support for dual emac mode.
In dual emac mode, the CPSW subsystem provides two independent ethernets.
This is implemented (as recommended by TI's TRM) with a mixture of switch
settings (vlans) and specific features of CPSW subsystem.
The driver was splitted to accommodate the shared parts (RX and TX rings
for example) while it still provides two independent ethernets.
Each of the ethernet ports driver has it's own set of MDIO registers among
the other private settings.
Previously this driver always operate in promisc mode, now the Switch ALE
(address table entry) is properly initialized and enabled.
The driver is also tested (and known to work) with both ports operating in
single port mode (active_slave 0 or 1).

[intrng] Migrate the intrng code from sys/arm/arm to sys/kern/subr_intr.c.
The ci20 port (by kan@) is going to reuse almost all of the intrng code
since the SoC in question looks suspiciously like someone took an ARM
SoC design and replaced the ARM core with a MIPS core.
* migrate out the code;
* rename ARM_ -> INTR_;
* rename arm_ -> intr_;
* move the interrupt flush routine from intr.c / intrng.c into
arm/machdep_intr.c - removing the code duplication and removing
the ARM specific bits from here.
Thanks to the Star Wars: The Force Awakens premiere line for allowing
me a couple hours of quiet time to finish the universe builds.
Tested:
* make universe
TODO:
* The structure definitions in subr_intr.c still includes machine/intr.h
which requires one duplicates all of the intrng definitions in
the platform code (which kan has done, and I think we don't have to.)
Instead I should break out the generic things (function declarations,
common intr structures, etc) into a separate header.

Remove all dregs of the old PPS driver from this code, in preparation for
redoing it as a separate driver. Now that each hardware timer is handled by
a separate instance of the timer driver, it no longer makes sense to bundle
the pps driver with the regular timecounter code. (When all 8 timers were
handled by one driver there was no choice about this.)
Split the hardware register definitions out to their own file, so that the
new pps driver (coming in a separate commit later) can share them.
With the PPS driver gone, the question of which hardware timer to use for
what purpose becomes much easier (some instances can't do the PPS capture).
Now we can just hardcore timer2 for eventtimer and timer3 for timecounter.
This also now only instantiates devices for the 2 hardware timers actually
used to implement eventtimer and timecounter. This is required so that
other drivers can come along and attach to other hardware timers to provide
other functionality. (In addition to PPS, this hardware can also do PWM
stuff, general pulse width and frequency measurements, etc. Maybe some
day we'll have drivers for those things.)

Extend TPS65217 support to be able to pull and decode battery
charger configuration and provide some basic control knobs to
set charger voltage and dump config on boot. Two loader tunables
have been added:
o hw.am335x_pmic.bootverbose set to 1 to get more info on the
boot;
o hw.am335x_pmic.vo: set to charger voltage to be applied on
kernel initialization time, supported values are "4.10V",
"4.15V", "4.20V" and "4.25V".
Cleanup code a bit in general, move TPS65217 register
definitions into a separate header, convert bit-banging
defines into bitmap structures.
Also threat the case when power source is neither "AC" nor "USB"
as "Battery", not "Unknown".

Switch TI platform support code from using FreeBSD's custom-baked DTS
files to vendor-provided ones. It should make easier to adopt platform
code to new revisions of hardware and to use DTS overlays for various
Beaglebone extensions (shields/capes).
Original dts filenames were not changed, they're now wrappers over dts
files provided by TI. So make sure you update .dtb files on your
devices as part of kernel update
GPIO addressing was changed: instead of one global /dev/gpioc0 there
are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for
instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25
on /dev/gpioc3
On Pandaboard serial console devices was changed from /dev/ttyu0 to
/dev/ttyu2 so you'll have to update /etc/ttys to get login prompt
on serial port in multiuser mode. Single user mode serial console
should work as-is

Add support to turn off Beaglebone with poweroff(8) or shutdown(8) -p.
To cut off the power we need to start the shutdown sequence by writing
the OFF bit on PMIC.
Once the PMIC is programmed the SoC needs to toggle the PMIC_PWR_ENABLE
pin when it is ready for the PMIC to cut off the power. This is done by
triggering the ALARM2 interrupt on SoC RTC.
The RTC driver only works in power management mode which means it won't
provide any kind of time keeping functionality. It only implements a way
to trigger the ALARM2 interrupt when requested.

Add a new sdhci quirk, SDHCI_QUIRK_WAITFOR_RESET_ASSERTED, to work around
TI OMAP controllers which will return the reset-in-progress bit as zero if
you read the status register too fast after setting the reset bit.
The zero is apparently from a stale snapshot of the internal state presented
in the interface register, and leads to a false indication that the reset
is complete when it either hasn't started yet or is in-progress. The
workaround is to first loop until the bit is seen as asserted, then do the
normal loop waiting to see it de-asserted.

Fix the i2c bus speed divisors for TI OMAP4 and AM335x.
For OMAP4, the old values for 1MHz gave a bus frequency of about 890KHz.
The new numbers hit 1MHz exactly.
For AM335x the prescaler values are adjusted to give a 24MHz clock for
all 3 standard speeds, as the manual recommends (as near as we can tell,
there are errors and typos apparent in the document). Also, 1MHz speed
is added, and has been tested successfully on a BeagleboneWhite board.

Allow i2c bus speed to be configured via hints, FDT data, and sysctl.
The current support for controlling i2c bus speed is an inconsistant mess.
There are 4 symbolic speed values defined, UNKNOWN, SLOW, FAST, FASTEST.
It seems to be universally assumed that SLOW means the standard 100KHz
rate from the original spec. Nothing ever calls iicbus_reset() with a
speed of FAST, although some drivers would treat it as the 400KHz standard
speed. Mostly iicbus_reset() is called with the speed set to UNKNOWN or
FASTEST, and there's really no telling what any individual driver will do
with those.
The speed of an i2c bus is limited by the speed of the slowest device on
the bus. This means that generally the bus speed needs to be configured
based on the board/system and the components within it. Historically for
i2c we've configured with device hints. Newer systems use FDT data and it
documents a clock-frequency property for i2c busses. Hobbyists and
developers are likely to want on the fly changes. These changes provide
all 3 methods, but do not require any existing drivers to change to use
the new facilities.
This adds an iicbus method, iicbus_get_frequency(dev, speed) that gets the
frequency for the requested symbolic speed. If the symbolic speed is SLOW
or if there is no speed configured for the bus, the returned value is
100KHz, always. Otherwise, if bus speed is configured by hints, fdt,
tunable, or sysctl, that speed is returned. It also adds a helper
function, iicbus_init_frequency() that any bus driver subclassed from
iicbus can initialize the frequency from some other source of info.
Initial driver implementations are provided for Freescale and TI.

Rewrite of ti_i2c based on gonzo's patch, fix the following bugs/problems:
. interrupt storm detected on "intr70:"; throttling interrupt source;
. Added access serialization on iicbus_transfer(), previously there was
no such protection and a new transfer could easily confuse the
controller;
. Add error checkings (i.e. stop the transfer when a error is detected
and do _not_ overwrite the previous error);
. On command done interrupt do not assume that the transfer was finished
sucessfully as we will receive the command done interrupt even after
errors;
. Simplify the FIFO handling;
. Reset the FIFO between the transfers as the FIFO may contain data from
the last (failed) transfer;
. Fix the iicbus speed for AM335x, which in turn will make better use of
the I2C noise filter (set to one internal clock cycle);
. Move the read and write handler to ithread instead of notifying the
requesting thread with wakeup(9);
. Fix the comments based on OMAP4 TRM.
The above changes allows me to read the EDID from my HDMI monitor on BBB
with gonzo's patches to support TDA19988 (which does 128 bytes reads) and
repeatedly scan the iicbus (with a modified i2c(8)) without lock up the bus.

FreeBSD, historically, has always used 8-bit addresses for i2c devices
(7-bit device address << 1), always leaving the room for the read/write bit.
This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them
compatible with 8-bit addresses. Previous to this commit an i2c device
would have different addresses depending on the controller it was attached
to (by example, when compared to any iicbb(4) based i2c controller), which
was a pretty annoying behavior.
Also, update the PMIC i2c address on beaglebone* DTS files to match the new
address scheme.
Now the userland utilities need to do the correct slave address shifting
(but it is going to work with any i2c controller on the system).

The ti_i2c controller only works in the master mode and the i2c address
passed on iicbus_reset() is used to set the controller slave address when
operating as an i2c slave (which isn't currently supported).
When talking to a slave, the slave address is correctly provided to
ti_i2c_tranfer().

Export two new settings for the AM335x PWM, the clock prescaler (clkdiv)
and the actual PWM frequency.
Enforce the maximum value for the period sysctl.
The frequency systcl now allows the direct setting of the PWM frequency (it
will try to find the better clkdiv and period for a given frequency, i.e.
the ones that will give the better PWM resolution).
This allows the use lower frequencies on the PWM. Without changing the
clock prescaler the minimum PWM frequency was 1.52kHz.
PWM frequencies checked with an osciloscope.

Eliminate one of the causes of spurious interrupts on armv6. The arm weak
memory ordering model allows writes to different devices to complete out
of order, leading to a situation where the write that clears an interrupt
source at a device can complete after a write that unmasks and EOIs the
interrupt at the interrupt controller, leading to a spurious re-interrupt.
This adds a generic barrier function specific to the needs of interrupt
controllers, and calls that function from the GIC and TI AINTC controllers.
There may still be other soc-specific controllers that need to make the call.

- Fix the setup of interrupts for banks 2 and 3 on AM335x.
On AM335x each one of the four GPIO banks has two physical interrupt
lines, so we now allocate resources and setup our interrupt handler for
all the (8) available interrupts.
On OMAP3 and OMAP4 there is only one interrupt for each GPIO bank (6
banks, 6 interrupts), but there are two set of registers where the
first one is used to setup the delivery of interrupts to the MPU and
the second set, setup the delivery of interrupts to the DSP.
On AM335x, each set of registers controls each one of the interrupt
lines.
- Remove nonexistent registers for OMAP4 and AM335x, replace their use with
the correct ones for these SoCs.
- Remove stray whitespace.
Based on OMAP3, OMAP4 and AM335x TRMs.

Various fixes to the ti_sdhci driver, mostly to make it work on Pandaboard.
- Don't allow high-speed mode on OMAP4 due to hardware erratum.
- Check the proper bit in the status register when waiting for the
controller to come out of reset.
- Add handling for the "non-removable" fdt property by always returning
"card is present" status.
- Add the non-removable property for the MMC card on a Beaglebone Black.
- Add the non-removable property for Pandaboard as a workaround.
For Pandaboard the card detect pin is handled by the twl6030 fpga device
which gets an interrupt on pin change and then has to query the fpga
for the actual status. We don't have code to do that yet.

Trivial changes/forced-commit to document previous change r264050 whose
description was eaten by the dog (or an editor crash or something).
Add variable-frequency support to the arm mpcore eventtimer driver.
This allows a platform's early init code to tell the mpcore driver that the
clock frequency can vary. That causes the mpcore driver to register an
eventtimer, but not a timecounter. The platform has to provide a time
counter using some other fixed-frequency clock, but can still use the
per-cpu goodness of the mpcore hardware for event timers.
When the platform support code does something to change the frequency of
the CPU clocks (power saving, thermal management) it must tell the mpcore
driver code about it using arm_tmr_change_frequency().

Call initarm_lastaddr() later in the init sequence, after establishing
static device mappings, rather than as the first of the initializations
that a platform can hook into. This allows a platform to allocate KVA
from the top of the address space downwards for things like static device
mapping, and return the final "last usable address" result after that and
other early init work is done.
Because some platforms were doing work in initarm_lastaddr() that needs to
be done early, add a new initarm_early_init() routine and move the early
init code to that routine on those platforms.
Rename platform_devmap_init() to initarm_devmap_init() to match all the

TI sdhci driver improvements, mostly related to fdt data...
Use the published compatible strings (our own invention, "ti,mmchs" is
still accepted as well, for now).
Don't blindly turn on 8-bit bus mode, because even though the conroller
supports it, the board has to be wired appropriately as well. Use the
published property (bus-width=<n>) and honor all the valid values (1,4,8).
The eMMC device on a Beaglebone Black is wired for 8-bit, update the dts.
The mmchs controller can inherently do both 1.8v and 3.0v on the first
device and 1.8v only on other devices, unless an external transceiver is
used. Set the voltage automatically for the first device and honor
the published fdt property (ti,dualvolt) for other devices.

The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a
couple quirks, which are now supported by sdhci(4) as of r254507.
This should work for all TI SoCs that use the MMCHS hardware, but it has
only been tested on AM335x right now, so this enables it on those platforms
but leaves the existing ti_mmchs driver in place for other OMAP variants
until they can be tested.
This initial incarnation lacks DMA support (coming soon). Even without it
this improves performance pretty noticibly over the ti_mmchs driver,
primarily because it now does multiblock IO.

memory-mapped device register as one of the arguments for the transfer.
Several scattered ad-hoc solutions have been converted to use this macro,
which now also serves to mark the places where a more complete fix needs
to be applied (after that fix has been designed).

Switch eventtimers(9) from using struct bintime to sbintime_t.
Even before this not a single driver really supported full dynamic range of
struct bintime even in theory, not speaking about practical inexpediency.
This change legitimates the status quo and cleans up the code.

Another overhaul of the CPSW driver for BeagleBone
Major changes:
* Finally tracked down the flow control setting that
seems to have been causing TX stalls and watchdog timeouts
* RX and TX paths now share a lot more code
* TX interrupt is no longer used; we instead GC finished
tx queue entries at the bottom of the start routine.
* TX start now queues fragmented packets directly; it only
invokes defrag() for occasional very fragmented packets.
* "sysctl dev.cpsw" dumps controller statistics and queue counts
* Host Error Interrupt will give extensive debugging information
if the controller chokes on the queued data.

While trying to track down the root cause for
TX stalls in this driver, I've also had some
time to evaluate the effectiveness of different
watchdog strategies.
This is the latest attempt, which consolidates
all of the watchdog logic in one place and
consistently detects TX stalls and resets within
a couple of seconds.

Overhauled CPSW driver for TI CPSW Ethernet module
(as used in AM335x SoC for BeagleBone).
Among other things:
* Watchdog reset doesn't hang the driver.
* Disconnecting cable doesn't hang the driver.
* ifconfig up/down doesn't hang the driver
* Out-of-memory no longer panics the driver.
Known issues:
* Doesn't have good support for fragmented packets
(calls m_defrag() on TX, assumes RX packets are never fragmented)
* Promisc and allmulti still unimplimented
* addmulti and delmulti still unimplemented
* TX queue still stalls (but watchdog now consistently recovers in ~5s)
* No sysctl monitoring
* Only supports port0
* No switch configuration support
* Not tested on anything but BeagleBone

PL310 driver update:
- Add pl310.disable tunable to disable L2 cache altogether. In
order to make sure that it's 100% disabled we use cache event
counters for cache line eviction and read allocate events
and panic if any of these counters increased. This is purely
for debugging purpose
- Direct access DEBUG_CTRL and CTRL might be unavailable in
unsecure mode, so use platform-specific functions for
these registers
- Replace #if 1 with proper erratum numbers
- Add erratum 753970 workaround
- Remove wait function for atomic operations
- Protect cache operations with spin mutex in order to prevent race condition
- Disable instruction cache prefetch and make sure data cache
prefetch is enabled in OMAP4-specific intialization

Merge the FDT versions of initarm.
The copies of initarm used on platforms with FDT support were almost
identical. The differences were pulled out into separate functions that
were called by initarm.
This change merges the, now identical, copies of initarm and a few of it's
support functions. This is a step towards a common kernel on ARMv6.
