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"

This pull request contains Broadcom ARM/ARM64/MIPS based SoCs changes
for 5.1, please pull the following:
- Stefan updates the BCM2835 SoC driver with downstream properties and
uses that to implement a reboot notifier to tell the VC4 firmware when
Linux on the ARM CPU is rebooting
- Eric adds a proper power domain driver for the BCM283x SoCs and
updates a bunch of drivers to have a better and clearer Device Tree
definition to support power domains/breaking up of functionality. This
requires converting the existing watchdog driver into a MFD and then
breaking up the functionality into separate drivers and finally
updating the DTS files to leverage the power domains information.
- Wei provides a fix for making a symbol static

Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board. Audio system topology,
clocking and power can all be controlled through the Lochnagar
controller chip, allowing the device under test to be used in
a variety of possible use cases.
As the Lochnagar is a fairly complex device this MFD driver
allows the drivers for the various features to be bound
in. Initially clocking, regulator and pinctrl will be added as
these are necessary to configure the system. But in time at least
audio and voltage/current monitoring will also be added.

The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config MFD_WM8350
drivers/mfd/Kconfig: bool
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
We delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
We replace module.h with init.h and export.h ; the latter since the
file does export some symbols.
Previous demodularizaion work has made wm8350_device_exit() no longer
used, so it is also removed from the 8350 core code.

This provides a free software alternative to raspberrypi-power.c's

where previously the vc4 driver had to try to force power off the
domain in order to trigger a reset.

DSI LCD panels describe an initialization sequence in the Video BIOS
Tables using so called MIPI sequences. One possible element in these
sequences is a PMIC specific element of 15 bytes.
Although this is not really an ACPI opregion, the ACPI opregion code is the
closest thing we have. We need to have support for these PMIC specific MIPI
sequence elements somwhere. Since we already instantiate a special platform
device for Intel PMICs for the ACPI PMIC OpRegion handler to bind to,
with PMIC specific implementations of the OpRegion, the handling of MIPI
sequence PMIC elements fits very well in the ACPI PMIC OpRegion code.
This commit adds a new intel_soc_pmic_exec_mipi_pmic_seq_element()
function, which is to be backed by a PMIC specific
exec_mipi_pmic_seq_element callback. This function will be called by the
i915 code to execture MIPI sequence PMIC elements.
