Pull i2c updates from Wolfram Sang: "The biggest news in this pull request is that it will start the last cycle of me handling the I2C subsystem. From 7.2. on, I will pass maintainership to Andi Shyti who has been maintaining the I2C drivers for a while now and who has done a great job in doing so. We will use this cycle for a hopefully smooth transition. Thanks must go to Andi for stepping up! I will still be around for guidance.

dt-bindings: i2c: realtek,rtl9301-i2c: extend for clocks and RTL9607C support

2026-04-01T22:09:21Z

Add the "realtek,rtl9607-i2c" compatible for i2c controller on the RTL9607C SoC series. Add a clocks property to the properties to describe the i2c reference clock and make it available for all the compatibles. This i2c reference clock is assumed to be coming from switchcore region via Lexra bus as the other SoC peripherals. According to the info available about the existing devices, they also have the i2c master controller clocks. RTL9607C requires the "realtek,scl" and "clocks" to be specified and so handle it under separate if check for "realtek,rtl9607-i2c".

dt-bindings: i2c: intel,ixp4xx-i2c: Convert to DT schema

2026-03-31T22:30:43Z

Convert the IOP3xx and IXP4xx XScale bindings to DT schema. This conversion also adds the interrupts property, as it is used by the driver and existing DTS files but was not documented in the original binding.

dt-bindings: i2c: dw: Remove unused bindings

2026-03-25T17:06:53Z

As stated in the d70f60ad964d ("i2c: designware: Remove not-going-to-be-supported code for Baikal SoC") the Baikal platforms are not supported and the respective driver code was removed. Remove the currently unused bindings.
