Merge tag 'i2c-for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "I2C core:

   - finally remove the I2C_COMPAT symbol after 15 years of deprecation

   - lock client addresses during initialization to prevent race
     conditions between different kinds of instantiation

   - use scoped foreach OF child loops

   - testunit cleanups and documentation improvements, as well as two
     new tests, one for repeated start and one for triggering SMBusAlert
     interrupts

  I2C host drivers:

   - DesignWare and Renesas I2C driver updates.

     The first has has undergone through a series of cleanups that have
     been sent to the mailing list a year ago for the first time and
     finally get merged in this pull request. They are many, from typos
     (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
     functions to librarieas) and many others.

   - all the DesignWare Kconfig options have been grouped under the
     I2C_DESIGNWARE_CORE and this required some adaptation in many of
     the kernel configuration files for different arm and mips boards

  Cleanups:

   - improve the exit path in the runtime resume function for the
     Qualcomm Geni platform

   - get rid of the unused "target_addr" parameter in the Intel LJCA
     driver

   - intialize the restart_flag in the MediaTek controller in one single
     place

   - constify a few global data structures in the virtio driver

   - simplify the bus speed handling in the Renesas driver init function
     making it more readable

   - improved probe function of the Renesas R-Car driver

   - switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
     SET_RUNTIME_PM_OPS()

   - iMX/MXC driver cleanups

   - use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
     and MPC drivers

  Refactoring:

   - Fix a potential out of boundary array access in the Nuvoton driver.

     This is not a bug fix because the issue could never occur due to
     hardware not having the properties listed in the array. The change
     makes the driver more future proof and, at the same time, silences
     code analyzers.

  Improvements:

   - several patches improving the runtime power management handling of
     the Renesas I2C (riic) driver

   - use a more descriptive adapter name in the Intel i801 driver to
     show the presence of the IDF feature

   - kill pending transactions when irq's can't complete their handling
     in the Intel Denverton (ismt) driver, triggering a timeout

  New Feature:

   - support fast mode plus in the Renesas I2C (riic) driver

  New support:

   - Added support for:
      - Renesas R9A08G045
      - Rockchip RK3576
      - KEBA I2C
      - Theobroma Systems Mule Multiplexer.

   - new i2c-keba.c driver

   - new driver for The Mule i2c multiplexer

  Core I2C framework:

   - move runtime PM functions in order to allow them to be accessed
     during device add

  Devicetree:

   - nVidia and Qualcomm binding improvements

   - get rid of redundant "multi-master" property in the aspeed binding

   - convert i2c-sprd binding to YAML

  AT24 updates:

  - document a new model from giantec in DT bindings"
