Shall I resubmit this patch separately from the big series for easier merging (perhaps also dropping the MAINTAINERS update until later, so as to minimize conflicts in linux-next)? It doesn't have any external dependencies, and the binding itself is rather boring/trivial. Best regards, Alexey

Rewrite the textual description for the WonderMedia I2C controller as YAML schema, and switch the filename to follow the compatible string. The controller only supports two bus speeds (100kHz and 400kHz) so restrict clock-frequency values accordingly.
