Pull i2c fixes from Wolfram Sang:
 "The I2C core gains documentation updates for the testunit, a cleanup
  regarding unneeded 'driver_data' and more sanity checks in the char
  device.

  For the host drivers, this release includes significant updates, with
  the primary change being the renaming from "master/slave" to
  "controller/target" to adhere to I2C v7 and SMBus 3.2 standards.

  New Support:

   - Added support for Intel Arrow Lake-H
   - Added I2C support in the Arioha SoC by linking the Mediatek I2C
     controller

  Cleanups:

   - Added the MODULE_DESCRIPTION() macro, resolving a modpost warning
     in the ALi 1563 Southbridge driver.
   - Constified the regmap_config declaration in the i2c-designware
     driver.
   - Improved the coding style in the Renesas R-Car driver by removing
     unnecessary semicolons after brackets.

  General improvements:

   - In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with
     RUNTIME_PM_OPS to enable waking up the controller during suspend()
     before suspend_noirq() kicks in.
   - Improved logging in the Xilinx driver.
   - Added a warning (WARN()) in the Renesas R-Car driver for spurious
     interrupts.

  DTS Changes:

   - Removed address-cell and size-cell from the Atmel at91sam, nVidia
     Tegra 20, and Samsung S3c2410 devices.
   - Fixed Texas Instruments OMAP4 I2C controller to comply with the
     i2c-controller.yaml schema.
   - Improved indentation in DTS examples for several I2C devices.
   - Converted the NXP LPC1788 binding to the dt-schema.
   - Added documentation for the compatible string thead,th1520-i2c.
   - Added the "power-domains" property for the Meson I2C driver.

  AT24 EEPROM driver changes:

   - add support for two new Microchip models
   - document even more new models in DT bindings (those use fallback
     compatibles so no code changes)"
