git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Arnd Bergmann:
"There are a couple of subsystems maintained by other people that merge
their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power
domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control and SoC
identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660 and
SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs"

Currently array of fix length PM_API_MAX is used to cache
the pm_api version (valid or invalid). However ATF based
PM APIs values are much higher then PM_API_MAX.
So to include ATF based PM APIs also, use hash-table to
store the pm_api version status.

The zynqmp_pm_set_suspend_mode() and zynqmp_pm_get_trustzone_version()
functions pass values as api_id into zynqmp_pm_invoke_fn
that are beyond PM_API_MAX, resulting in an out-of-bounds access:
drivers/firmware/xilinx/zynqmp.c: In function 'zynqmp_pm_set_suspend_mode':

Replace the resulting undefined behavior with an error return.
This may break some things that happen to work at the moment
but seems better than randomly overwriting kernel data.
I assume we need additional fixes for the two functions that now
return an error.

Add sysfs interface to set boot health status from user space.
Add API used by this interface to communicate with firmware.
If PMUFW is compiled with CHECK_HEALTHY_BOOT, it will check the
healthy bit on FPD WDT expiration. If healthy bit is set by a user
application running in Linux, PMUFW will do APU only restart. If
healthy bit is not set during FPD WDT expiration, PMUFW will do
system restart.

not include an option to set a scope, i.e. which parts of the system to

next shutdown request. When the next shutdown is performed, the platform
specific portion of PSCI-system_off can use the chosen shutdown scope.
