Driver updates for ARM SoCs, these contain various things that touch
the drivers/ directory but got merged through arm-soc for practical
reasons:
- Rockchip rk3368 gains power domain support
- Small updates for the ARM spmi driver
- The Atmel PMC driver saw a larger rework, touching both
arch/arm/mach-at91 and drivers/clk/at91
- All reset controller driver changes alway get merged through
arm-soc, though this time the largest change is the addition
of a MIPS pistachio reset driver
- One bugfix for the NXP (formerly Freescale) i.MX weim bus driver

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.

- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes.

As usual, this is the massive branch we have for each release. Lots of
various updates and additions of hardware descriptions on existing hardware,
as well as the usual additions of new boards and SoCs.
This is also the first release where we've started mixing 64- and 32-bit
DT updates in one branch.
(Specific details on what's actually here and new is pretty easy to tell
from the diffstat, so there's little point in duplicating listing it here.)

"As usual, this is the massive branch we have for each release. Lots
of various updates and additions of hardware descriptions on existing
hardware, as well as the usual additions of new boards and SoCs.
This is also the first release where we've started mixing 64- and
32-bit DT updates in one branch.
(Specific details on what's actually here and new is pretty easy to
tell from the diffstat, so there's little point in duplicating listing
it here)"

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.

Currently firmware file name is included in the DTS. This is not scalable
as user has to change the DTS if they need upgrade to a new firmware.
Instead, add the firmware file name in the driver itself. As long as there
is no API change, new firmware upgrade is easy and require no driver
change. User is expected to copy the firmware image to the file system
and add a sym link to the new firmware for doing an upgrade. Driver add
a array of firmware file names to search for the available firmware blobs.
This scheme also prepare the driver for future changes to API if ever
happens. In such case it is assumed that driver needs to change to
accommodate the new firmware and new firmware file name will get added to
the array.
Also update the DT document to remove the firmware attribute and add
description about firmware in the driver documentation.

This is a collection of a few late fixes and other misc. stuff that

The bulk of the changes are for samsung/exynos SoCs for some changes
that needed a few minor reworks so ended up a bit late. The others
are mainly for qcom SoCs: a couple fixes and some DTS updates.
There's one conflict with drivers/cpufreq/exynos-cpufreq.c because

that they have to (also) go in through our tree.
For this release, we have merged in part of the reset controller tree

It turns out that existing U-Boots will dereference NULL pointers
if the device tree does not have cell-index in the portal nodes.
No patch has yet been merged adding device tree nodes for this binding
(except a dtsi that has not yet been referenced), nor has any driver
yet been merged making use of the binding, so it's not too late to
change the binding in order to keep compatibility with existing
U-Boots.

The Allwinner SoCs have a handful of SRAM that can be either mapped to be
accessible by devices or the CPU.
That mapping is controlled by an SRAM controller, and that mapping might
not be set by the bootloader, for example if the device wasn't used at all,
or if we're using solutions like the U-Boot's Falcon Boot.
We could also imagine changing this at runtime for example to change the
mapping of these SRAMs to use them for suspend/resume or runtime memory
rate change, if that ever happens.
These use cases require some API in the kernel to control that mapping,
exported through a drivers/soc driver.
This driver also implement a debugfs file that shows the SRAM found in the
system, the current mapping and the SRAM that have been claimed by some
drivers in the kernel.

Driver updates for v4.1. Some of these are for drivers/soc, where we find more
and more SoC-specific drivers these days. Some are for other driver subsystems
where we have received acks from the appropriate maintainers.
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.
- Anoter set of cleanusp to the OMAP GPMC code.

This patch adds automatic configuration for the ADM CRCI muxing required to

the correct TCSR ADM CRCI MUX value that must be programmed so that the DMA

The Keystone Navigator DMA driver sets up the dma channels and flows for
the QMSS(Queue Manager SubSystem) who triggers the actual data movements
across clients using destination queues. Every client modules like
NETCP(Network Coprocessor), SRIO(Serial Rapid IO) and CRYPTO
Engines has its own instance of packet dma hardware. QMSS has also
an internal packet DMA module which is used as an infrastructure
DMA with zero copy.
Initially this driver was proposed as DMA engine driver but since the
hardware is not typical DMA engine and hence doesn't comply with typical
DMA engine driver needs, that approach was naked. Link to that
discussion -
https://lkml.org/lkml/2014/3/18/340
As aligned, now we pair the Navigator DMA with its companion Navigator
QMSS subsystem driver.

The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
the main hardware sub system which forms the backbone of the Keystone
Multi-core Navigator. QMSS consist of queue managers, packed-data structure
processors(PDSP), linking RAM, descriptor pools and infrastructure
Packet DMA.
The Queue Manager is a hardware module that is responsible for accelerating
management of the packet queues. Packets are queued/de-queued by writing or
reading descriptor address to a particular memory mapped location. The PDSPs
perform QMSS related functions like accumulation, QoS, or event management.
Linking RAM registers are used to link the descriptors which are stored in
descriptor RAM. Descriptor RAM is configurable as internal or external memory.
