The suspend() hook in the cpuidle_ops struct is always called on
the cpu entering idle, which means that the cpu parameter passed
to the suspend hook always corresponds to the local cpu, making
it somewhat redundant.
This patch removes the logical cpu parameter from the ARM
cpuidle_ops.suspend hook and updates all the existing kernel
implementations to reflect this change.

This patch adds support for several power domains on Raspberry Pi,
including USB (so it can be enabled even if the bootloader didn't do
it), and graphics.
This patch is the combined work of Eric Anholt (who wrote USB support
inside of the Raspberry Pi firmware driver, and wrote the non-USB
domain support) and Alexander Aring (who separated the original USB
work out from the firmware driver).

The Kconfig currently controlling compilation of this code is:
drivers/soc/mediatek/Kconfig:config MTK_SCPSYS
drivers/soc/mediatek/Kconfig: bool "MediaTek SCPSYS Support"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

accelerated en- and decoding of various video standards including
H.265, H.264 and VP8 at 4K resolutions and up to 60 fps.
Besides the multimedia features it also comes with a variety of I/O

Configure linking RAM for both queue managers also in case
when only linking RAM 0 is specified in device tree.
Currently hwqueue driver configures linking RAM(s) to be used
cooperatively by the QMs (shared mode). Therefore if both
queue managers are used then both must be configured with
exactly the same linking RAM info (base address and size)
independent of the number of linking RAM(s) specified in the
device tree.
For proper operation only one linking RAM is required and in most
cases this can be internal one as long as it is able to handle
the number of descriptors used in the system.
Current driver code however skips configuration of second
queue manager if second linking RAM is not specified.
If the configuration for the QM2 is missing there will be
a crash when it tries to push/pop descriptors from its queues.

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.

This fixes the corner-case where the pmic is initialized by the bootloader, but
not the pmic watchdog.
Add support for active wakeup to the scpsys. This allows to keep the power of
a scpsys domain during suspend state.
With version v4.3 new subsystem clocks are added to the clock dirver. In late
init the kernel turns off all unused clocks. This can provoke a hang if
the kernel tries to access the venc and venc_lt power domain registers.
Add the necessary parent clocks for this power domains to
the scpsys so that no random hang happens.
The bootloader of mt6589, mt8135 and mt1827 does not turn on the arm-arch-timer.
As there is no opensource bootloader in the near future for this architectures
we enable the arch timer at kernel boot. We need the arch timer for SMP boot.

SMEM is a software construct built on top of a DDR reserved region
and sometimes a device memory region called RPM message ram. Having
the RPM message ram in the smem DT node's reg property leads to the
smem node being located in different places depending on if the
message ram is being used or not. Let's add a qcom specific
property, qcom,rpm-msg-ram, and point to the device memory from
the SMEM node via a phandle. As SMEM is a software construct, it
really needs to reside at the root of the DT regardless of whether
it's using the message ram or not.

based and word based. We have 4 pointers to these info
structures, when we really only need two to point to the
different types of structures. Encapsulate the byte based and

in the smd channel structure by two.
