Wolfram Sang 1b3073291d i2c-host updates for v6.13, part 1
Improvements and Refactoring:
 
  - All controllers using the 'remove_new' callback have been
    reverted to use the 'remove' callback.
 
  - Makefile improvements (switched from '*-objs' to '*-y')
 
  - Intel SCH controller underwent significant refactoring:
    - Improved usage of private data references.
    - Transitioned to memory-mapped I/O functions.
    - Adopted 'devm' functions for resource management.
    - Added kernel-doc compatible comments.
    - Used 'const' where applicable.
    - Numerous smaller refinements.
    This brings love and a modern look to the driver.
 
  - Additional cleanups in the DesignWare driver.
 
  - PIIX4 driver updates:
    - Exposed functions and definitions in the header file to
      enable usage by other drivers (e.g., AMD ASF).
 
  - Nuvoton NPCM I2C controller:
    - Enhanced read/write operations and bus error (BER) flag
      management to address corner cases that could lead to
      timeouts.
 
  - Qualcomm CCI driver received several cleanups.
 
  - iMX/MXC:
    - Improved message handling to reduce I2C protocol overhead.
    - Refactored DMA/non-DMA read/write and bus polling mechanisms
      to achieve this.
 
 New Features:
 
  - i2c-cadence:
    - Added support for atomic transfers.
    - Refactored to group generic code into separate functions.
 
  - Qualcomm CCI:
    - Added support for a 32MHz serial engine clock.
 
  - Added support for:
    - HJMC01 DesignWare ACPI HID.
    - ACPI documentation for PIIX4.
 
 Deprecated Features:
 
  - Dropped support for AMD756 S4882 and NFORCE2 S4985.
 
 New Hardware Support:
 
  - Added support for:
    - Intel Panther Lake.
    - AMD ASF.
    - S32G2/S32G3 SoCs.
    - Realtek RTL I2C Controller.
 
  - New drivers:
    - 'i2c-amd-asf-plat.c' for AMD ASF.
    - 'i2c-rtl9300.c' for Realtek RTL.
 
 Fixes:
 
  - AMD ASF driver:
    - Fixed an uninitialised 'len' variable.
 
 Devicetree Updates:
 
  - Documented Qualcomm SDM670.
  - Added 'PIC64GX' compatibility to Microchip Core I2C binding.
  - Added support for S32G.
