Driver changes for omaps for genpd for v5.11 merge window
This series of changes allows booting am335x with genpd and
device tree data without the legacy platform data. Also at
least am437x can be booted with gendp with power domain and
dts data. The SoC specific dts changes will be a separate
pull request.
We need the following driver changes merged before the dts
changes can be done:
- platform code needs a few improvments to probe l4_wkup first
for clocks, and to bail out when there is no platform data
- ti-sysc driver needs a non-urgent fix for asserting rstctrl
reset only after disabling the clocks, to probe modules with
no known control registers, and added quirk handling for gpmc
devices
- omap-prm driver needs a non-urgent fix for reset status bit,
support added for pm_clk, and then we add the rest of am335x
power domain data
- clock driver for am335x needs to keep l3_main clock enabled
with genpd for suspend and resume to work
- wkup_m3 remoteproc driver needs support added for reset
control if available instead of the legacy pdata callbacks
- pm33xx driver needs PM runtime support added for genpd
The am335x specific driver changes for the clock, wkup_m3,
pm33xx and remoteproc drivers are quite trivial and have not
caused merge conflicts in Linux next. I did not get acks for
these changes except from Santosh but had already pushed out
the branch already at that point. So I've added the related
driver maintainers to Cc.

The Exynos ChipID driver on Exynos SoCs has only informational
purpose - to expose the SoC device in sysfs. No other drivers
depend on it so there is really no benefit of initializing it early.
Instead, initialize everything with arch_initcall which:
1. Allows to use dev_info() as the SoC bus is present (since
core_initcall),
2. Could speed things up because of execution in a SMP environment
(after bringing up secondary CPUs, unlike early_initcall),
3. Reduces the amount of work to be done early, when the kernel has to
bring up critical devices.

Memory controller drivers for v5.11 - Tegra SoC
There is a bigger work from Dmitry Osipenko around Tegra SoC memory
controller drivers, mostly towards adding interconnect support and
integration with devfreq. This work touches all Tegra memory controller
drivers and also few other SoC-related parts. It's not yet finished but
the intermediate stage seems ready to merge.
Beside that Tegra 210 memory controller got few fixes and received new
swgroups (work of Nicolin Chen).

The local variable 'cpumask_t mask' is in the stack memory, and its address
is assigned to 'desc->affinity' in 'irq_set_affinity_hint()'.
But the memory area where this variable is located is at risk of being

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.

Samsung SoC drivers changes for v5.11
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.

Allwinner MBUS and DMA-ops rework
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.
