Do you plan to grow on them, like add more compatibles here? Otherwise all this could be in one binding. Best regards, Krzysztof

Otherwise all > this could be in one binding. The blk ctrls are for different functions. We may expand the bindings to add more properties for the blk ctrls, but I am not sure as of now. I could merge them into one binding except the one with mux-controller if you prefer. Or leave them as is, still separate binding files. Thanks, Peng. > > Best regards, > Krzysztof
