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"

Reduced Serial Bus (RSB) is an Allwinner proprietery interface
used to communicate with PMICs and other peripheral ICs.

RSB is a two-wire push-pull serial bus that supports 1 master
device and up to 15 active slave devices.

CCI-500 provides 8 event counters which can count any of the
supported events independently. The PMU event id is a 9-bit
value made of two parts.
	bits [8:5] - Source port
			0x0-0x6 Slave Ports
			0x8-0xD Master Ports
			0xf     Global Events to CCI
			0x7,0xe Reserved
	bits [0:4] - Event code (specific to each type of port)

The generic CCI-500 controlling interface remains the same with CCI-400.
However there are some differences in the PMU event counters.
 - No cycle counter
 - Upto 8 counters(4 in CCI-400)
 - Each counter area is 64K(4K in CCI400)
 - The counter0 starts at offset 0x10000 from the base of CCI

  The larger parts of this branch are:

   - MediaTek support for their PMIC wrapper interface, a high-level
     interface for talking to the system PMIC over a dedicated I2C
     interface.

   - Qualcomm SCM driver has been moved to drivers/firmware.  It's used
     for CPU up/down and needs to be in a shared location for arm/arm64
     common code.

   - cleanup of ARM-CCI PMU code.

Add MIPS Common Device Memory Map (CDMM) support in the form of a bus in
the standard Linux device model. Each device attached via CDMM is
discoverable via an 8-bit type identifier and may contain a number of
blocks of memory mapped registers in the CDMM region. IRQs are expected
to be handled separately.

Due to the per-cpu (per-VPE for MT cores) nature of the CDMM devices,
all the driver callbacks take place from workqueues which are run on the
right CPU for the device in question, so that the driver doesn't need to
be as concerned about which CPU it is running on. Callbacks also exist
for when CPUs are taken offline, so that any per-CPU resources used by
the driver can be disabled so they don't get forcefully migrated. CDMM
devices are created as children of the CPU device they are attached to.

Any existing CDMM configuration by the bootloader will be inherited,
however platforms wishing to enable CDMM should implement the weak
mips_cdmm_phys_base() function (see asm/cdmm.h) so that the bus driver
knows where it should put the CDMM region in the physical address space
if the bootloader hasn't already enabled it.

A mips_cdmm_early_probe() function is also provided to allow early boot
or particularly low level code to set up the CDMM region and probe for a
specific device type, for example early console or KGDB IO drivers for
the EJTAG Fast Debug Channel (FDC) CDMM device.

This patch separates the PMU driver code from the low level
CCI driver code and enables the PMU driver for ARM64.

Introduces config options for both.

 ARM_CCI400_PORT_CTRL	- controls the low level driver code for
			  CCI400 ports.
 ARM_CCI400_PMU		- controls the PMU driver code
 ARM_CCI400_COMMON	- Common defintions for CCI400

This patch also changes:
 ARM_CCI - common code for probing the CCI devices. This can be
   used for adding support for newer CCI versions(e.g, CCI-500).
