Pull ARM SoC driver updates from Olof Johansson:
 "Driver updates for ARM SoCs.  Some for SoC-family code under
  drivers/soc, but also some other driver updates that don't belong
  anywhere else.  We also bring in the drivers/reset code through
  arm-soc.

  Some of the larger updates:

   - Qualcomm support for SMEM, SMSM, SMP2P.  All used to communicate
     with other parts of the chip/board on these platforms, all
     proprietary protocols that don't fit into other subsystems and live
     in drivers/soc for now.

   - System bus driver for UniPhier

   - Driver for the TI Wakeup M3 IPC device

   - Power management for Raspberry PI

  + Again a bunch of other smaller updates and patches"

<content type='text'>
The UniPhier System Bus is an external bus that connects on-board
devices to the UniPhier SoC.  Each bank (chip select) is dynamically
mapped to the CPU-viewed address base via the bus controller.  The
bus controller must be configured before any access to the bus.

This driver parses the "ranges" property of the System Bus node and
initialized the bus controller.  After the bus becomes ready, devices
below it are populated.

Note:
Each bank can be mapped anywhere in the supported address space;
there is nothing preventing us from assigning bank 0 on 0x42000000,
0x43000000, or anywhere as long as such region is not used by others.
So, the "ranges" is just one possible software configuration, which
does not seem to fit in device tree because device tree is a hardware
description language.  However, of_translate_address() requires
"ranges" in every bus node between CPUs and device mapped on the CPU
address space.  In other words, "ranges" properties must be statically
defined in device tree.  After some discussion, I decided the dynamic
address reassignment by the driver is too bothersome.  Instead, the
device tree should provide a reasonable translation setup that the OS
can rely on.

Pull ARM SoC driver updates from Olof Johansson:
 "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"
