Subject: [GIT PULL 4/6] ARM: SoC driver updates for v4.4
As we've enabled multiplatform kernels on ARM, and greatly done away with
the contents under arch/arm/mach-*, there's still need for SoC-related
drivers to go somewhere.
Many of them go in through other driver trees, but we still have
drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
that might be shared between ARM and ARM64 (or just in general makes
sense to not have under the architecture directory).
This branch contains mostly such code:
- Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
with power management blocks on these SoCs for use by clock, regulator and
bus frequency drivers.
- Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
- Drivers for ARM's SCPI (System Control Processor). Not to be confused with
PSCI (Power State Coordination Interface). SCPI is used to communicate with
the assistant embedded cores doing power management, and we have yet to see
how many of them will implement this for their hardware vs abstracting in
other ways (or not at all like in the past).
- To make confusion between SCPI and PSCI more likely, this release also
includes an update of PSCI to interface version 1.0.
- Rockchip support for power domains.
- A driver to talk to the firmware on Raspberry Pi.
