Pull ARM SoC driver updates from Arnd Bergmann:
"As usual, the drivers/tee and drivers/reset subsystems get merged
here, with the expected set of smaller updates and some new hardware
support. The tee subsystem now supports device drivers to be attached
to a tee, the first example here is a random number driver with its
implementation in the secure world.
Three new power domain drivers get added for specific chip families:
- Broadcom BCM283x chips (used in Raspberry Pi)
- Qualcomm Snapdragon phone chips
- Xilinx ZynqMP FPGA SoCs
One new driver is added to talk to the BPMP firmware on NVIDIA
Tegra210
Existing drivers are extended for new SoC variants from NXP, NVIDIA,
Amlogic and Qualcomm"

Compiling the bcm2835-rpi.dtsi with W=1 leads to the following warning:
Warning (avoid_unnecessary_addr_size): /soc/firmware: unnecessary
#address-cells/#size-cells without "ranges" or child "reg" property
Fix this by removing these unnecessary properties.

The GRAFX domain only contains V3D, and this driver should be the only
accessor of V3D (firmware usage gets disabled when V3D is in the DT),
so we can safely make Linux control the GRAFX and GRAFX_V3D power
domains.

All RPi 1 and 2 boards used the PWM (audio out) on pin 40 and 45.
So it was easy to define them in bcm2835-rpi.dtsi. Starting with RPi 3
this wont work anymore, because it uses pin 40 and 41. Furthermore the
Zero variants doesn't have audio out.
This patch fixes this pin conflict by moving the PWM node to the board-level.
Change summary:
RPi 3 B: PWM1 45 -> 41
Zero, Zero W: PWM disabled
all other: no functional change

Pull ARM SoC device tree updates from Arnd Bergmann:
"This is the usual set of changes for device trees, with over 700
non-merged changesets. There is an ongoing set of dtc warning fixes
and the usual bugfixes, cleanups and added device support.
The most interesting bit as usual is support for new machines listed
below:
- The Allwinner H6 makes its debut with the Pine-H64 board, and we
get two new machines based on its older siblings: the H5 based
OrangePi Zero+ and the A64 based Teres-I Laptop from Olimex. On the
32-bit side, we add The Olimex som204 based on Allwinner A20, and
the Banana Pi M2 Zero development board (based on H2).
- NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
development board and p2888 CPU module.
- The Nuvoton npcm750 is a BMC that was newly added, for now we only
support running on the evaluation board.
- STmicroelectronics stm32 gains support for the stm32mp157c and two
evaluation boards.
- The Toradex Colibri board family grows a few members based on the
i.MX6ULL variant.
- The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6 family
of chips.
- The Phytec phyBOARD Mira is a family of industrial boards based on
i.MX6. For now, four models get added.
- TI am335x based PDU-001 is an industrial embedded machine used for
traffic monitoring
- The Aspeed platform now supports running on the BMC on the Qualcomm
Centriq 2400 server
- Samsung Exynos4 based Galaxy S3 is a family of mobile phones
Qualcomm msm8974 based Galaxy S5 is a rather different phone made
by the same company.
- The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
for the various boards made by Xilinx themselves, as well as the
Digilent Zybo Z7.
- The ARM Versatile family now supports the "IB2" interface board.
- The Renesas H2 based "Stout" and the H3 based Salvator-X are more
evaluation boards named after a kind of beer, as most of them are.
The r8a77980 (V3H) based "Condor" apparently doesn't follow that
tradition. ;-)
- ROC-RK3328-CC is a simple developement board from the Libre
Computer Project, based on the Rockchips RK3328 SoC
- Haiku is another development board plus Qseven module based on
Rockchips RK3368 and made by Theobroma Systems"

Until RPI 3 and Zero W the pl011 (uart0) was always on pin 14/15. So in
order to take care of them and other boards in the future,
we need to define UART pinmuxing on board level.
This work based on Eric Anholt's patch "ARM: bcm2385: Don't force pl011
onto pins 14/15." and Fabian Vogt's patch "ARM64: dts: bcm2837: assign
uart0 to BT and uart1 to pin headers".

sdcard access with the sdhost controller is faster.
Read access (dd with 64k blocks on rpi2):
CONFIG_MMC_SDHCI_IPROC: 11-12 MB/s
CONFIG_MMC_BCM2835: 19-20 MB/s
Differences on write access are pretty much in the noise.

This file is included from DTS files under arch/arm64 too (via
broadcom/bcm2837-rpi-3-b.dts and broadcom/bcm2837.dtsi). There is a desire
not to have skeleton.dtsi for ARM64. See commit 3ebee5a2e141 ("arm64: dts:
kill skeleton.dtsi") for rationale for its removal.
As well as the addition of #*-cells also requires adding the device_type to
the rpi memory node explicitly.
Note that this change results in the removal of an empty /aliases node from
bcm2835-rpi-a.dtb and bcm2835-rpi-a-plus.dtb. I have no hardware to check
if this is a problem or not.
It also results in some reordering of the nodes in the DTBs (the /aliases
and /memory nodes come later). This isn't supposed to matter but, again,
I've no hardware to check if it is true in this particular case.
