Signed-off-by: Joachim Eastwood <redacted> --- Hi, AT91RM9200 is gaining DT support now so let's add an id to the i2c driver. Tested on custom RM9200 board. Since the driver doesn't support pinctrl muxing yet I had to add pinctrl hogs for the i2c pins in my dts for it to work.
IIRC the i2c IP have quite a lots of issue on rm9200 and until sam9g45 it not recommended to use it instead use i2c-gpio Best Regards, J.
