Updates for SoC specific drivers include a few subsystems that
have their own maintainers but send them through the soc tree:
TEE/OP-TEE:
- Add tracepoints around calls to secure world
Memory controller drivers:
- Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
- Add debug statistics to Tegra20 memory controller
- Update Tegra bindings and convert to dtschema
ARM SCMI Firmware:
- Support for modular SCMI protocols and vendor specific extensions
- New SCMI IIO driver
- Per-cpu DVFS
The other driver changes are all from the platform maintainers
directly and reflect the drivers that don't fit into any other
subsystem as well as treewide changes for a particular platform.
SoCFPGA:
- Various cleanups contributed by Krzysztof Kozlowski
Mediatek:
- add MT8183 support to mutex driver
- MMSYS: use per SoC array to describe the possible routing
- add MMSYS support for MT8183 and MT8167
- add support for PMIC wrapper with integrated arbiter
- add support for MT8192/MT6873
Tegra:
- Bug fixes to PMC and clock drivers
NXP/i.MX:
- Update SCU power domain driver to keep console domain power on.
- Add missing ADC1 power domain to SCU power domain driver.
- Update comments for single global power domain in SCU power domain
driver.
- Add i.MX51/i.MX53 unique id support to i.MX SoC driver.
NXP/FSL SoC driver updates for v5.13
- Add ACPI support for RCPM driver
- Use generic io{read,write} for QE drivers after performance optimized
for PowerPC
- Fix QBMAN probe to cleanup HW states correctly for kexec
- Various cleanup and style fix for QBMAN/QE/GUTS drivers
OMAP:
- Preparation to use devicetree for genpd
- ti-sysc needs iorange check improved when the interconnect target module
has no control registers listed
- ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as we
now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
- omap-prm driver needs to enable autoidle retention support for omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of using
builtin_platform_driver_probe for deferred probe to work
Raspberry Pi:
- Fix-up all RPi firmware drivers so as for unbind to happen in an
orderly fashion

Almost all SoC code changes this time are for the TI OMAP
platform, which continues its decade-long quest to move from
describing a complex SoC in code to device tree.
Aside from this, the Uniphier platform has a new maintainer
and some platforms have minor bugfixes and cleanups that were
not urgent enough for v5.12.

The intent here was to return negative error codes but it actually
returns positive values. The problem is that type promotion with
ternary operations is quite complicated.
"ret" is an int. "copied" is a u32. And the snoop_file_read() function
returns long. What happens is that "ret" is cast to u32 and becomes
positive then it's cast to long and it's still positive.
Fix this by removing the ternary so that "ret" is type promoted directly
to long.

Another smaller set of fixes for three of the Arm platforms:
TI OMAP:
Fix swapped mmc device order also for omap3 that got changed with the
recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the aliases
should be board specific, all the mmc device instances are all there in
the SoC, and we do probe them by default so that PM runtime can idle the
devices if left enabled from the bootloader.
Qualcomm Snapdragon:
This bypasses the, recently introduced, interconnect handling in the
GENI (serial engine) driver when running off ACPI, as this causes the
GENI probe to fail and the Lenovo Yoga C630 to boot without keyboard
and touchpad.
Allwinner:
One 32kHz clock fix for the beelink gs1, a CD polarity fix for the SoPine,
some MAINTAINERS maintainance, and a clk / reset switch to our headers.

calling convention, in particular on SC7180, and fixes a few small
issues in the same.
It introduces additonal sanity checks of the size of loaded segments in
the MDT loader and adds a missing error in the return path of
pdr_register_listener().
It makes it possible to specify the OEM specific firmware path in the
wcn36xx control (and WiFi) driver.
Lastly it adds a missing path specifier in the MAINTAINERS' entry and

caused a regression.

OMAP4_SHA2MD5_CLKCTRL clock node for disable for unused clocks
- Add aliases for omap4/5 mmc to put the slots back into the right
order again
- Fix typo for bionic voltage controllers that accidentally use mpu
for all instances instead of mpu, core and iva
- Fix random hangs for droid4 caused by missing fix from TI Android
kernel tree to do a dummy smc call on cpuidle wakeup path
NXP i.MX:

- Fix address typo in i.MX8MM/Q IOMUXC_SD1_DATA0_GPIO2_IO2 definition.

In order to move omap4/5 and dra7 to probe with devicetree data and genpd,
we need to patch the related drivers to prepare.
These are mostly ti-sysc interconnect target module driver changes and soc
init changes. However, there are minor changes to other drivers too. There
are changes for pci-dra7xx probe, omap-prm idle configuration, and a omap5
clock change:
- ti-sysc needs iorange check improved when the interconnect target module
has no control registers listed
- ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as we
now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and
dra7
- omap-prm driver needs to enable autoidle retention support for omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of using
builtin_platform_driver_probe for deferred probe to work
There are also few minor non-urgent fixes:
- soc init code pdata_quirks_init_clocks should be static
- ti-sysc has few unneeded semiconon typos
- ti-sysc can use kzalloc instead of kcalloc for a single element

This reverts commit 048eb908a1 ("soc: qcom-geni-se: Add interconnect
support to fix earlycon crash")
ICC core and platforms drivers supports sync_state feature, which
ensures that the default ICC BW votes from the bootloader is not
removed until all it's consumers are probes.
The proxy votes were needed in case other QUP child drivers
I2C, SPI probes before UART, they can turn off the QUP-CORE clock
which is shared resources for all QUP driver, this causes unclocked
access to HW from earlycon.
Given above support from ICC there is no longer need to maintain
proxy votes on QUP-CORE ICC node from QUP wrapper driver for early
console usecase, the default votes won't be removed until real
console is probed.

The SW-initiated power gate toggling is dropped by PMC if there is
contention with a HW-initiated toggling, i.e. when one of CPU cores is
gated by cpuidle driver. Software should retry the toggling after 10
microseconds on Tegra20/30 SoCs, hence add the retrying. On Tegra114+ the
toggling method was changed in hardware, the TOGGLE_START bit indicates
whether PMC is busy or could accept the command to toggle, hence handle
that bit properly.
The problem pops up after enabling dynamic power gating of 3D hardware,
where 3D power domain fails to turn on/off "randomly".
The programming sequence and quirks are documented in TRMs, but PMC
driver obliviously re-used the Tegra20 logic for Tegra30+, which strikes
back now. The 10 microseconds and other timeouts aren't documented in TRM,
they are taken from downstream kernel.
