Reset controller updates for v5.11
This tag adds support for sharing pulsed resets under certain
conditions. For example, when multiple drivers go through a
suspend-resume cycle, a reset line they share can be triggered
again during resume.
Further, the reset-meson driver now can be built as a module, the
reset-socfpga driver properly releases its memory region in the
probe error path, and reset-ti-syscon driver uses regmap_write_bits()
instead of regmap_update_bits() to support devices without status
readback.

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

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.

soc: ti: Fix reference imbalance in knav_dma_probe
The patch fix two reference leak.
1) pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to call put operation will result in
reference leak.
2) The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced.
We fix it by: 1) adding call pm_runtime_put_noidle or
pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable
in error handling, to keep usage counter and disable depth balanced.
