69cab2d1bf Fix locking in bcm2835_audio driver
- Move all VCHI activity to worker thread: channel methods are called with
    non-sleepable lock held and VCHI uses sleepable lock.

- In worker thread use sx(9) lock instead of mutex(9) for the same reason.

563193fd0c Add initial Raspberry Pi 3 support
RPI3 kernel config builds kernel compatible with latest upstream device
tree and firmware: https://github.com/raspberrypi/firmware/tree/master/boot
As of today it's 597c662a613df1144a6bc43e5f4505d83bd748ca

Default console is PL01x, so pi3-disable-bt dt overlay should be configured
in config.txt and stock U-Boot should be patched to use proper serial port.

Yet unsupported: SMP, VCHIQ, RNG driver. RNG requires some work due to
upstream device tree incompatibility.

32cb200f78 Add touchscreen support for the official 7" RPi touch display
Technically touchscreen chip is FT5406 but all hardware
communication is performed by VideCore and only final results
are presented to ARM part through memory region shared between
VC and ARM.

evdev is used as userland interface. FT5406 supports up to
10 touchpoints, but for now driver emulates single touch device
because I do not have GUI bits to test this functionality.

Driver is not enabled in default config for RPI and RPI2

a1acc06f4f Random bit generator (RBG) driver for RPi and RPi2.
Summary:
This driver supports the following methods to trigger gathering random bits from the hardware:
1. interrupt when the FIFO is full (default) fed into the harvest queue
2. callout (when BCM2835_RNG_USE_CALLOUT is defined) every second if hz is less than 100, otherwise hz / 100, feeding the random bits into the harvest queue

If the kernel is booted with verbose enabled, the contents of the registers will be dumped after the RBG is started during the attach routine.

Author: hackagadget_gmail.com (Stephen J. Kiernan)

Test Plan: Built RPI2 kernel and booted on board. Tested the different methods to feed the harvest queue (callout, interrupt) and the interrupt driven approach seems best. However, keeping the other method for people to be able to experiment with.

After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C
reference and as result, the temperature read in sysctl(8) now exibits a
+0.1C difference.

This commit fix the kernel references to match the reference value used in
sysctl(8) after r285994.

bc90a48ccf Add OF_prop_free function as a counterpart for OF_*prop_alloc
- Introduce new OF API function OF_prop_free to free memory allocated by
  OF_getprop_alloc and OF_getencprop_alloc. Current code just calls free(9)
  with M_OFWPROP memory class which assumes knowledge about OF_*prop_alloc
  functions' internals and leads to unneccessary code coupling

- Convert some of the free(..., M_OFWPROP) instances to OF_prop_free

Files affected by this commit are the ones I was able to test on real
hardware. The rest of free(..., M_OFWPROP) instances will be handled with
idividual maintainers

cd642c88a1 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.
