This branch contains platform-related driver updates for ARM and ARM64,
these are the areas that bring the changes:
New drivers:
- Driver support for Renesas R-Car V3M (R8A77970)
- Power management support for Amlogic GX
- A new driver for the Tegra BPMP thermal sensor
- A new bus driver for Technologic Systems NBUS
Changes for subsystems that prefer to merge through arm-soc:
- The usual updates for reset controller drivers from Philipp Zabel,
with five added drivers for SoCs in the arc, meson, socfpa, uniphier
and mediatek families.
- Updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,
Heiner Kallweit and Lorenzo Pieralisi.
Changes specific to some ARM-based SoC
- The Freescale/NXP DPAA QBMan drivers from PowerPC can now work
on ARM as well.
- Several changes for power management on Broadcom SoCs
- Various improvements on Qualcomm, Broadcom, Amlogic, Atmel, Mediatek
- Minor Cleanups for Samsung, TI OMAP SoCs

Pull ARM SoC driver updates from Arnd Bergmann:
"This branch contains platform-related driver updates for ARM and

[ NOTE! This doesn't work without the previous ARM SoC device-tree pull,
because the R8A77970 driver is missing a header file that came from
that pull.
The fact that this got merged afterwards only fixes it at this point,
and bisection of that driver will fail if/when you walk into the
history of that driver. - Linus ]

For this to work, either your bootloader needs to enable the CDMM
