Pull ARM SoC driver updates from Arnd Bergmann:
"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
- Support for RPi's PoE hat PWM bus
Qualcomm
- Improved detection for SCM calling conventions
- Support for OEM specific wifi firmware path
- Added drivers for SC7280/SM8350: RPMH, LLCC< AOSS QMP"

This reverts commit 6ac9b61786cc64ae5cbfb69413137656f72e8204.
This commit was required because at that time, ioread/iowrite
functions were sub-optimal on powerpc/32 compared to the
architecture specific in_/out_ IO accessors.
But there are now equivalent since
commit 894fa235eb4c ("powerpc: inline iomap accessors").

The opening comment mark '/**' is used for kernel-doc comments.
There are certain comments in include/linux/fsl/guts.h which follows this
syntax, but the content inside does not comply with kernel-doc.
E.g., opening comment for "Freecale 85xx and 86xx Global Utilties
register set" follows kernel-doc syntax(i.e., '/**'), but the content
inside does not comply with any kernel-doc specification (function,
struct, etc).
This causes unwelcomed warning from kernel-doc:
"warning: expecting prototype for Freecale 85xx and 86xx Global Utilties register set(). Prototype was for __FSL_GUTS_H__() instead"
Replace all such comment occurrences with general comment format,
i.e. '/*' to pervent kernel-doc from parsing these.

IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE)
zynqmp_pm_get_eemi_ops() was removed in commit 4db8180ffe7c: "Firmware: xilinx:
Remove eemi ops for fpga related APIs", but not in IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE).
Any driver who want to communicate with PMC using EEMI APIs use the functions provided
for each function
This removed zynqmp_pm_get_eemi_ops() in IS_REACHABLE(CONFIG_ZYNQMP_FIRMWARE), and also
modify the documentation for this driver.

More Qualcomm driver updates for 5.13
This improves the Qualcomm SCM driver logic related to detecting the
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
fixes a bunch of kerneldoc issues in various drivers.

Add debug statistics collection support. The statistics is available
via debugfs in '/sys/kernel/debug/mc/stats', it shows percent of memory
controller utilization for each memory client. This information is
intended to help with debugging of memory performance issues, it already
was proven to be useful by helping to improve memory bandwidth management
of the display driver.

ARM SCMI updates for v5.13
The major and big addition this time is to support modularisation of
individual SCMI protocols thus enabling to add support for vendors'
custom SCMI protocol. This changes the interface provided by the SCMI
driver to all the users of SCMI and hence involved changes in various
other subsystem SCMI drivers. The change has been split with a bit of
transient code to preserve bisectability and avoiding one big patch bomb
changing all the users.
This also includes SCMI IIO driver(pulled from IIO tree) and support for
per-cpu DVFS.

Notification private data is currently accessible via handle->notify_priv,
this data was indeed meant to be private to the notification core support
and not to be accessible by SCMI drivers. Make it private hiding it
inside instance descriptor struct scmi_info and accessible only via
dedicated helpers.

PLLE has a hardware power sequencer logic which is a state machine
that can power on/off PLLE without any software intervention. The
sequencer has two inputs, one from XUSB UPHY PLL and the other from
SATA UPHY PLL. PLLE provides reference clock to XUSB and SATA UPHY
PLLs. When both of the downstream PLLs are powered-off, PLLE hardware
power sequencer will automatically power off PLLE for power saving.
XUSB and SATA UPHY PLLs also have their own hardware power sequencer
logic. XUSB UPHY PLL is shared between XUSB SuperSpeed ports and PCIE
controllers. The XUSB UPHY PLL hardware power sequencer has inputs
from XUSB and PCIE. When all of the XUSB SuperSpeed ports and PCIE
controllers are in low power state, XUSB UPHY PLL hardware power
sequencer automatically power off PLL and flags idle to PLLE hardware
power sequencer. Similar applies to SATA UPHY PLL.
PLLE hardware power sequencer has to be enabled after both downstream
sequencers are enabled.
This commit adds two helper functions:
1. tegra210_plle_hw_sequence_start() for XUSB PADCTL driver to enable
PLLE hardware sequencer at proper time.
2. tegra210_plle_hw_sequence_is_enabled() for XUSB PADCTL driver to
check whether PLLE hardware sequencer has been enabled or not.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers
Driver changes for omaps for genpd support for v5.13
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
* tag 'omap-for-v5.13/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:

When unbinding the firmware device we need to make sure it has no
consumers left. Otherwise we'd leave them with a firmware handle
pointing at freed memory.
Keep a reference count of all consumers and introduce rpi_firmware_put()
which will permit automatically decrease the reference count upon
unbinding consumer drivers.

TIOCSSERIAL is a horrid, underspecified, legacy interface which for most
serial devices is only useful for setting the close_delay and
closing_wait parameters.
The closing_wait parameter determines how long to wait for the transfer
buffers to drain during close and the default timeout of 30 seconds may
not be sufficient at low line speeds. In other cases, when for example
flow is stopped, the default timeout may instead be too long.
Add generic support for TIOCSSERIAL and TIOCGSERIAL with handling of the
three common parameters close_delay, closing_wait and line for the
benefit of all USB serial drivers while still allowing drivers to
implement further functionality through the existing callbacks.
This currently includes a few drivers that report their base baud clock
rate even if that is really only of interest when setting custom
divisors through the deprecated ASYNC_SPD_CUST interface; an interface
which only the FTDI driver actually implements.
Some drivers have also been reporting back a fake UART type, something
which should no longer be needed and will be dropped by a follow-on
patch.

A single USB function can be implemented using a group of interfaces and
this is for example commonly used for Communication Class devices.
Add support for multi-interface functions to USB serial core and export
an interface that allows drivers to claim a second sibling interface.
The interface could easily be extended to allow claiming further
interfaces if ever needed.
When a driver claims a sibling interface in probe(), core allocates
resources for any bulk in, bulk out, interrupt in and interrupt out
endpoints found also on the sibling interface.
Disconnect is implemented so that unbinding either interface will
release the other interface while disconnect() is called precisely once.
Similarly, suspend() is called when the first sibling interface is
suspended and resume() is called when the last sibling interface is
resumed by USB core.
