Linus Torvalds 592fa9532d Merge branch 'i2c/for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:

 - new drivers for Silicon Labs CP2615 and the HiSilicon I2C unit

 - bigger refactoring for the MPC driver

 - support for full software nodes - no need to work around with only
   properties anymore

 - we now have 'devm_i2c_add_adapter', too

 - sub-system wide fixes for the RPM refcounting problem which often
   caused a leak when an error was encountered during probe

 - the rest is usual driver updates and improvements

Linus Torvalds 37f00ab4a0 ARM: SoC drivers for v5.13
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

Marek Behún 39930213e7 i2c: mv64xxx: Fix random system lock caused by runtime PM
I noticed a weird bug with this driver on Marvell CN9130 Customer
Reference Board.

Sometime after boot, the system locks with the following message:
 [104.071363] i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0

The system does not respond afterwards, only warns about RCU stalls.

This first appeared with commit e5c02cf541 ("i2c: mv64xxx: Add runtime
PM support").

With further experimentation I discovered that adding a delay into
mv64xxx_i2c_hw_init() fixes this issue. This function is called before
every xfer, due to how runtime PM works in this driver. It seems that in
order to work correctly, a delay is needed after the bus is reset in
this function.

Since there already is a known erratum with this controller needing a
delay, I assume that this is just another place this needs to be
applied. Therefore I apply the delay only if errata_delay is true.

Chris Packham bc72675228 i2c: mpc: make interrupt mandatory and remove polling code
All the in-tree dts files that use one of the compatible strings from
i2c-mpc.c provide an interrupt property. By making this mandatory we
can simplify the code.

Chris Packham 65171b2df1 i2c: mpc: Make use of i2c_recover_bus()
Move the existing calls of mpc_i2c_fixup() to a recovery function
registered via bus_recovery_info. This makes it more obvious that
recovery is supported and allows for a future where recovery is
triggered by the i2c core.

Dmitry Torokhov 5b5475826c i2c: ensure timely release of driver-allocated resources
More and more drivers rely on devres to manage their resources, however
if bus' probe() and release() methods are not trivial and control some
of resources as well (for example enable or disable clocks, or attach
device to a power domain), we need to make sure that driver-allocated
resources are released immediately after driver's remove() method
returns, and not postponed until driver core gets around to releasing
resources. To fix that we open a new devres group before calling
driver's probe() and explicitly release it when we return from driver's
remove().

Yicong Yang d62fbdb99a i2c: add support for HiSilicon I2C controller
Add HiSilicon I2C controller driver for the Kunpeng SoC. It provides
the access to the i2c busses, which connects to the eeprom, rtc, etc.

The driver works with IRQ mode, and supports basic I2C features and 10bit
address. The DMA is not supported.

bus frequency mode information, so add a public one that everyone
can make use of.

Yicong Yang 07740c92ae i2c: core: add managed function for adding i2c adapters
Some I2C controller drivers will only unregister the I2C
adapter in their .remove() callback, which can be done
by simply using a managed variant to add the I2C adapter.

So add the managed functions for adding the I2C adapter.
