Merge tag 'i2c-host-6.13-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow
i2c-host updates for v6.13, part 1 Major 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 Features: - i2c-cadence added support for atomic transfers. - Qualcomm CII added 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 Deprecated Features: - Dropped outdated support for AMD756 S4882 and NFORCE2 S4985.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 Support: - Added support for: - Intel Panther Lake (new ID) - AMD ASF (new driver) - S32G2/S32G3 SoCs (new ID) - Realtek RTL I2C Controller (new driver) - HJMC01 DesignWare ACPI HID (new ID) - PIC64GX to Microchip Core (new ID) - Qualcomm SDM670 to Qualcomm CCI (new ID)
