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- Dropped outdated support for AMD756 S4882 and NFORCE2 S4985.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)
