Pull SoC driver updates from Arnd Bergmann:
"The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware
drivers.
- Arm FF-A firmware support gains support for v1.1 specification
features, in particular notification and memory transaction
descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive,
amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and
more.
In particular, this contains portions of the treewide conversion to

The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. Many schemas for
phandle-array properties aren't clear in the schema which case applies
though the description usually describes it.
The array of phandles case boils down to needing:
items:
maxItems: 1
The phandle plus args cases should typically take this form:
items:
- items:
- description: A phandle
- description: 1st arg cell
- description: 2nd arg cell
With this change, some examples need updating so that the bracketing of
property values matches the schema.

"These are all the driver updates for SoC specific drivers. There are a
couple of subsystems with individual maintainers picking up their
patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this tree this
time. There are only minor changes, but they depend on other tegra
driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process. This
depends on a small sound driver change that is included here as
well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains a
mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for the
"Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed BMCs,
something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better
suspend/resume support"

Since MSM8916 is an ARM v8 64-bit SoC the CPU cores are normally booted
using "psci" or "spin-table". Unfortunately, some devices come with signed
32-bit-only firmware without ARM64 and PSCI support. This setup is easy to
support since it's very similar to older 32-bit only Qualcomm SoCs
(e.g. MSM8226) and only requires adding a few new definitions to already
existing drivers.
Document the qcom,msm8916-smp enable-method. It is actually just an alias
of qcom,msm8226-smp since it should be implemented identically.
The enable-method is only valid on ARM32 and must not be used on ARM64.

The CLKSCREW attack [0] exposed security vulnerabilities in energy management
implementations where untrusted software had direct access to clock and
voltage hardware controls. In this attack, the malicious software was able to
place the platform into unsafe overclocked or undervolted configurations. Such
configurations then enabled the injection of predictable faults to reveal
secrets.
Many Arm-based systems used to or still use voltage regulator and clock
frameworks in the kernel. These frameworks allow callers to independently
manipulate frequency and voltage settings. Such implementations can render
systems susceptible to this form of attack.
Attacks such as CLKSCREW are now being mitigated by not having direct and
independent control of clock and voltage in the kernel and moving that
control to a trusted entity, such as the SCP firmware or secure world
firmware/software which are to perform sanity checking on the requested
performance levels, thereby preventing any attempted malicious programming.
With the advent of such an abstraction, there is a need to replace the
generic clock and regulator bindings used by such devices with a generic
performance domains bindings.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

Pull ARM devicetree updates from Arnd Bergmann:
"Most of the commits are for additional hardware support and minor
fixes for existing machines for all the usual platforms: qcom,
amlogic, at91, gemini, mediatek, ti, socfpga, i.mx, layerscape,
uniphier, rockchip, exynos, ux500, mvebu, tegra, stm32, renesas,
sunxi, broadcom, omap, and versatile.
The conversion of binding files to machine-readable yaml format
continues, along with fixes found during the validation. Andre
Przywara takes over maintainership for the old Calxeda Highbank
platform and provides a number of updates.
The OMAP2+ platforms see a continued move from platform data into dts
files, for many devices that relied on a mix of auxiliary data in
addition to the DT description
A moderate number of new SoCs and machines are added, here is a full
list:
- Two new Qualcomm SoCs with their evaluation boards: Snapdragon 865
(SM8250) is the current high-end phone chip, and IPQ6018 is a new
WiFi-6 router chip.
- Mediatek MT8516 application processor SoC for voice assistants,
along with the "pumpkin" development board
- NXP i.MX8M Plus SoC, a variant of the popular i.MX8M, along with an
evaluation board.
- Kontron "sl28" board family based on NXP LS1028A
- Eleven variations of the new i.MX6 TechNexion Pico board, combining
the "dwarf", "hobbit", "nymph" and "pi" baseboards with i.MX6/i.MX7
SoM carriers
- Three additional variants of the Toradex Colibri board family, all
based on versions of the NXP i.MX7.
- The Pinebook Pro laptop based on Rockchip RK3399
- Samsung S7710 Galaxy Xcover 2, a 2013 vintage Android phone based
on the ST-Ericsson u8500 platform
- DH Electronics DHCOM SoM and PDK2 rev. 400 carrier based on
STMicroelectronics stm32mp157
- Renesas M3ULCB starter kit for R-Car M3-W+
- Hoperun HiHope development board with Renesas RZ/G2M
- Pine64 PineTab tablet and PinePhone phone, both based on Allwinner
A64
- Linutronix Testbox v2 for the Lamobo R1 router, based on Allwinner
A20
- PocketBook Touch Lux 3 ebook reader, based on Allwinner A13"
