Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver updates from Arnd Bergmann:
"The most noteworthy SoC driver changes this time include:

- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.

- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.

- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl"
interface that was a little controversial at first, but the version
we merged solved that by not exposing arbitrary firmware calls to
user space.

- The Amlogic Meson platform gains a "canvas" driver that is used for
video processing and shared between different high-level drivers.

The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:

- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.

- The Mediatek mt8183 and mt6765 SoC platforms gain support for their
respective power management chips.

- A new driver for NXP i.MX8, which need a firmware interface for
power management.

- The SCPI firmware interface now contains support estimating power
usage of performance states

- The NVIDIA Tegra "pmc" driver gains a few new features, in
particular a pinctrl interface for configuring the pads.

- Lots of small changes for Qualcomm, in particular the "smem" device
driver.

- Some cleanups for the TI OMAP series related to their sysc
controller.

Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"

arm64: zynqmp: SoC changes for v4.20

- Adding firmware API for SoC with debugfs interface
Firmware driver communicates to Platform Management Unit (PMU) by using
SMC instructions routed to Arm Trusted Firmware (ATF). Initial version
adds support for base firmware driver with query and clock APIs.

EEMI spec is available here:

Firmware-debug provides debugfs interface to all APIs.
Debugfs can be used to call firmware APIs with required
parameters.

Usage:
* Calling firmware API through debugfs:
# echo "<api-name> <arg1> .. <argn>" > /sys/.../zynqmp-firmware/pm

* Read output of last called firmware API:
# cat /sys/.../zynqmp-firmware/pm

Refer ug1200 for more information on these APIs:
* https://www.xilinx.com/support/documentation/user_guides/ug1200-eemi-api.pdf

Add basic debugfs file to get API version.
