Merge tag 'i2c-for-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "Core:

   - drivers can now use a GPIO as a side channel for SMBus Alerts using
     a generic binding

   - regular stuff like mem leak fix, Makefile maintenance...

  Host improvements and refactoring:

   - All controllers using the 'remove_new' callback have been reverted
     to use the 'remove' callback

   - Intel SCH controller underwent significant refactoring, this brings
     love and a modern look to the driver

   - PIIX4 driver refactored to enable usage by other drivers (e.g., AMD
     ASF)

   - iMX/MXC improved message handling to reduce protocol overhead:
     Refactored DMA/non-DMA read/write and bus polling mechanisms to
     achieve this.

   - ACPI documentation for PIIX4

  New host features:

   - i2c-cadence support for atomic transfers

   - Qualcomm CII support for a 32MHz serial engine clock

  Deprecated features:

   - Dropped outdated support for AMD756 S4882 and NFORCE2 S4985. If
     somebody misses this, Jean will rewrite support using the proper
     i2c mux framework.

  New hardware IDs for existing drivers:

   - Intel Panther Lake

   - S32G2/S32G3 SoCs

   - HJMC01 DesignWare ACPI HID

   - PIC64GX to Microchip Core

   - Qualcomm SDM670 to Qualcomm CCI

  New drivers:

   - AMD ASF

   - Realtek RTL I2C Controller

  at24 updates:

   - add support for the lockable page on ST M24256E"
