According to Tegra X1 TRM, there are missing swgroups in the
tegra210_swgroups list. So this patch adds them to the list.
Note that the TEGRA_SWGROUP_GPU (in list) should be actually
TEGRA_SWGROUP_GPUB (in TRM), yet TEGRA_SWGROUP_GPU (in TRM) is not being
used -- only TEGRA_SWGROUP_GPUB (in TRM) is. So this patch does not add
TEGRA_SWGROUP_GPU (in TRM) and keeps TEGRA_SWGROUP_GPU (in list)
as it is.

Hardware issue:
- Reading register RCPM_IPPDEXPCR1 always return zero, this causes
system firmware could not get correct information and wrongly do
clock gating for all wakeup source IP during system suspend. Then
those IPs will never get chance to wake system.
Workaround:
- Copy register RCPM_IPPDEXPCR1's setting to register SCFG_SPARECR8
to allow system firmware's psci method read it and do things accordingly.

1. Limit the big.LITTLE cpuidle driver to Peach-Pit/Pi Chromebooks only
because these are the only platforms were the driver works properly.
2. Convert the Exynos CLKOUT driver to a full module which solves
boot-probe ordering issues (e.g. if device nodes in DTS are moved).
This also brings modularization and compile testing.
3. Few minor cleanups in documentation and code.

assumed across all of SCMI implementation and, as such, all currently
existent names do not explicitly state their endianness.

The Allwinner SoCs have a number of high-bandwidth devices connected to
a memory bus with a different RAM mapping than the CPU.
This was addressed before through drivers setting the DMA offsets
directly, and subsequently changed to calls to dma_direct_set_offset.
However that wasn't really meant to be exported to modules (and thus
drivers). The duplicated code also led to small inconsistencies across
drivers in how we dealt with DT backward compatibility.
Move all that DMA setup code into a platform bus notifier to share that
code and remove the export on dma_direct_set_offset.

sensorUnits enumeration table of Distributed Management Task Force(DMTF)
specification number DSP 0248 (Platform Level Data Model for Platform

replica of the sensorUnits enumeration table.
Let us just update the table as per SCMI v2.0 specification.

The pl353-smc driver uses module_amba_driver so it has a build
dependency on CONFIG_ARM_AMBA:
/usr/bin/arm-linux-gnueabi-ld: drivers/memory/pl353-smc.o: in function `pl353_smc_driver_init':
pl353-smc.c:(.init.text+0x10): undefined reference to `amba_driver_register'
However it still can be compile tested on platforms other than ARM,
which in practice is limited to those selecting ARM_AMBA (so only
ARM64).
