chip's state has a DPRINTF, with things that happen repeatedly at debug=2
level and things that happen frequently (like per-transfer IO) at debug=3.

# 292080 11-Dec-2015 imp

Create a USB_PNP_INFO and use it to export the existing PNP
tables. Some drivers needed some slight re-arrangement of declarations
to accommodate this. Change the USB pnp tables slightly to allow
better compatibility with the system by moving linux driver info from
start of each entry to the end. All other PNP tables in the system
have the per-device flags and such at the end of the elements rather
that at the beginning.

# 286385 06-Aug-2015 ian

Return the current ftdi bitbang mode with the UFTDIIOC_GET_BITMODE ioctl.

The ftdi chip itself has a "get bitmode" command that doesn't actually
return the current bitmode, just a snapshot of the gpio lines. The chip
apparently has no way to provide the current bitmode.

This implements the functionality at the driver level. The driver starts
out assuming the chip is in UART mode (which it will be, coming out of
reset) and keeps track of every successful set-bitmode operation so that
it can always return the current mode with UFTDIIOC_GET_BITMODE.


# 286382 06-Aug-2015 ian

Add support to the uftdi driver for reading and writing the serial eeprom

# 267985 27-Jun-2014 gjb

Revert r267961, r267973:

These changes prevent sysctl(8) from returning proper output,
such as:

1) no output from sysctl(8)
2) erroneously returning ENOMEM with tools like truss(1)
or uname(1)
truss: can not get etype: Cannot allocate memory


# 267961 27-Jun-2014 hselasky

Extend the meaning of the CTLFLAG_TUN flag to automatically check if
there is an environment variable which shall initialize the SYSCTL
during early boot. This works for all SYSCTL types both statically and
dynamically created ones, except for the SYSCTL NODE type and SYSCTLs
which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to
be used in the case a tunable sysctl has a custom initialisation
function allowing the sysctl to still be marked as a tunable. The
kernel SYSCTL API is mostly the same, with a few exceptions for some
special operations like iterating childrens of a static/extern SYSCTL
node. This operation should probably be made into a factored out
common macro, hence some device drivers use this. The reason for
changing the SYSCTL API was the need for a SYSCTL parent OID pointer
and not only the SYSCTL parent OID list pointer in order to quickly
generate the sysctl path. The motivation behind this patch is to avoid
parameter loading cludges inside the OFED driver subsystem. Instead of
adding special code to the OFED driver subsystem to post-load tunables
into dynamically created sysctls, we generalize this in the kernel.

Other changes:
- Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask"
to "hw.pcic.intr_mask".
- Removed redundant TUNABLE statements throughout the kernel.
- Some minor code rewrites in connection to removing not needed
TUNABLE statements.
- Added a missing SYSCTL_DECL().
- Wrapped two very long lines.
- Avoid malloc()/free() inside sysctl string handling, in case it is
called to initialize a sysctl from a tunable, hence malloc()/free() is
not ready when sysctls from the sysctl dataset are registered.
- Bumped FreeBSD version to indicate SYSCTL API change.

# 264934 25-Apr-2014 ian

The FTDI product ID we've been calling BEAGLEBONE is actually TI XDS100V2,
a jtag debugging product, which was used on early Beaglebone boards (later
boards used a standard FTDI 2232C product ID). Change the name accordingly,
and also add an entry for XDS100V3, the latest version of that product
which has its own new product ID number.


# 264923 25-Apr-2014 ian

Remove device type from the uftdi_devs table, enhance the jtag-skip feature.

Device type and revision is now determined from the bcdDevice field and
doesn't need to be in the table at all. The feature that skips creation
of /dev/ttyU* entries for jtag and gpio interfaces is enhanced:

- The feature is now optional, but enabled by default. A tunable and
sysctl are available to control it: hw.usb.uftdi.skip_jtag_interfaces.
- We no longer assume interface #0 is the only jtag interface. Up to
eight interfaces per chip can be flagged as jtag. (Current ftdi chips
support a max of 4 interfaces; this leaves room for growth.)
- Some manufacturers don't change the product ID or use the same ID for
different devices intended for both serial-comms and jtag/gpio use.
Often while the product ID is the same, the product name string is
different, so it's now possible to search for the product name in a
table of strings and get the set of non-tty interfaces from that table.

# 264149 05-Apr-2014 ian

Add ioctl(2) calls to uftdi(4) to access bitbang, MPSSE, CPU_FIFO, and
other modes supported by the FTDI serial adapter chips.

In addition to adding the new ioctls, this change removes all the code
that reset the chip at attach and open/close time, and also the code
that turned on RTS/CTS flow control on open without any permission to do
so (that was just always a bug in the driver).

When FTDI chips are configured as GPIO or MPSSE or other special-purpose
uses by an attached serial eeprom, the chip will power on with certain
pins driven or floating, and it's important that the driver not do
anything to the chip to perturb that unless it receives a specific
command to do so. When used for "plain old serial comms" the chip
powers on into the right mode and never needs to be reset while it's
running to operate properly, so this change is transparent to most users.

# 264031 02-Apr-2014 ian

Use 2K buffers for IO to help achieve full device speed, rather than the
default wMaxPacketSize (64 or 512 bytes). This actually helps older FTDI
devices (which were USB 1/full speed) more than the new H-series high
speed, but even for the new chips it helps cut the number of interrupts
when doing very high speed (3-12mbaud).


# 264010 01-Apr-2014 ian

Support serial speeds up to 12mbaud with newer FTDI chips.

Recent FDTI chips have the ability to operate at up to 12mbps. The newer
chips with faster clocks have the same usb vendor/product IDs as the older
chips; the bcdDevice field must be used to detect the newer versions. This
change includes a new function to do that instead of using just the IDs from
the vendor/product table.

The code to choose the baud clock divisor is completely rewritten. In
addition to supporting the new higher clock rates, the rewrite fixes a
longstanding bug in the old code which put the high bits of the fractional
part of the divisor into the wrong place in the wIndex field. That bug
was mostly harmless -- it accidentally didn't affect standard baud rates
and would only show up when using relatively fast non-standard rates.

# 239055 05-Aug-2012 hselasky

Update the list of devices supported by the FTDI driver. It might be

driver detects this run-time and not compile time based on the bcdDevice
field of the USB device descriptor. Some of the ID's in usbdevs are not
sorted according to the product ID value. Please feel free to fix this.

Bring in USB4BSD, Hans Petter Selasky rework of the USB stack
that includes significant features and SMP safety.

This commit includes a more or less complete rewrite of the *BSD USB
stack, including Host Controller and Device Controller drivers and
updating all existing USB drivers to use the new USB API:

1) A brief feature list:

- A new and mutex enabled USB API.

- Many USB drivers are now running Giant free.

- Linux USB kernel compatibility layer.

- New UGEN backend and libusb library, finally solves the "driver
unloading" problem. The new BSD licensed libusb20 library is fully
compatible with libusb-0.1.12 from sourceforge.

- New "usbconfig" utility, for easy configuration of USB.

- Full support for Split transactions, which means you can use your
full speed USB audio device on a high speed USB HUB.

- Full support for HS ISOC transactions, which makes writing drivers
for various HS webcams possible, for example.

- Full support for USB on embedded platforms, mostly cache flushing
and buffer invalidating stuff.

- Safer parsing of USB descriptors.

- Autodetect of annoying USB install disks.

- Support for USB device side mode, also called USB gadget mode,
using the same API like the USB host side. In other words the new
USB stack is symmetric with regard to host and device side.

- Support for USB transfers like I/O vectors, means more throughput
and less interrupts.

2) To enable the driver at runtime:

2.a) Unload all existing USB modules. If USB is compiled into the
kernel then you might have to build a new kernel.

2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same
base name like the kernel device option.
