MFC r328201:

Convert extres/phy to kobj model. Similarly as other extres pseudo-drivers,
implement phy by using kobj model. This detaches it from provider device, so
single device driver can export multiple different phys. Additionally, this
allows phy to be subclassed to more specialized drivers, like is USB OTG phy,
or PCIe phy with hot-plug capability.

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.

MFC r309538:

Fixes for NVIDIA Tegra124 clocks:
- EMC clock have standard peripheral clock block. Use it. - Implement full
frequency set method for PLLD2. This PLL
is used as HDMI pixel clock so we must be able to set it to wide range of
frequencies, within 5% tolerance allowed by HDMI specification. Due to
this, full state space search (over m, n, p fields) is necessary.

MFC r308286,r308287:

r308286:
TEGRA: Add basic driver for memory controller. For now, it only reports
memory and SMMU access errors.
r308287:
TEGRA: Fix numerous issues in clock code. Define and export clocks related
to XUSB driver.

MFC r306442,r306444,r306445,r306550:

r306442:
TEGRA: Add support for MULTIDELAY option.
r306444:
TEGRA: Don't include files already included by system or arch configs.
r306445:
TEGRA: Return back kern_clocksource.c into tegra config file. It was
removed in r306444 by mistake.
r306550:
TEGRA: Extend timeout for PLLs lock to 5 ms. Real lock time for PLLA has
been very near to old limit.

MFC r306262, r306267, r310021: (needed to avoid conflicts on later merges)

Remove bus_dma_get_range and bus_dma_get_range_nb on armv6. We only need
this on a few earlier arm SoCs.

Restrict where we need to define fdt_fixup_table to just PowerPC and
Marvell.

Add the missing void to function signatures in much of the arm code.

MFC r306551,r307557:

r306551:
TEGRA: Fix bindings for cpufreq and coretemp drivers, it was broken in
r306477. Correct a description for coretemp driver.
r307557:
TEGRA: Attach cpufreq and coretemp drivers only on tegra124 SoC. It's
needed by GENERIC kernel.

r307556:
TEGRA: Really implement early printf. The original version was cut&pasted
from another SoC.
r307637:
TEGRA: Raise minimum voltage for CPU, original 0.9 V was too optimistic.
While I'm in, remove duplicated line from CPU frequency table.

TEGRA: Rename (cut & pasted) genahci to tegra_ahci. Make device class

- use DEFINE_CLASS_0() for driver classes - unify driver names - cleanup
driver definitions and bindings

MFC r302523,r302528:

r302523:
Add clk_get_by_ofw_node_index, which is like clk_get_by_ofw_index but
operates on a specific OF node instead of the pass in device's OF node.
r302528:
EXTRES: Add OF node as argument to all <foo>_get_by_ofw_<bar>() functions.
In some cases, the driver must handle given properties located in specific
OF subnode. Instead of creating duplicate set of function, add 'node' as
argument to existing functions, defaulting it to device OF node.

ARM: SEV/WFE instructions are implemented starting from ARMv6K, use it

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.

Add a MULTIDELAY option to allow the ARM kernel to have multiple DELAY
implementations. Early in the boot the kernel will use an approximate,
however after the timer has been probed it will switch to a more accurate

TEGRA: Fix CPU frequency switching.
The PLL_X, base CPU frequency source, doesn't have a bypass switch and thus
we must use another frequency source for CPU while changing its frequency.
PLL_P is ideal for this, it runs at 480MHz and CPU can be clocked at this
frequency at any CPU voltage.

Import basic support for Nvidia Jetson TK1 board and tegra124 SoC.
The following pheripherals are supported: UART, MMC, AHCI, EHCI, PCIe, I2C,
PMIC, GPIO, CPU temperature and clock.

Note: The PCIe driver is pure mash at this moment. It will be reworked
immediately when both D5237 and D2579 enter the current tree.
