Fine with me. Can switch over to
Documentation/devicetree/bindings/input/matrix-keymap.txt

Maybe samsung-keypad should also be converted because it's subnodes
structure duplicates exactly the same thing (row,col,code) in a
different way, and we both were distracted by it, ignoring
matrix-keymap.txt? Or is it already too late (both samsung-keypad and
matrix-keypad both being standards in use) and we should put a
recommendation into one of them to use the other one for new designs?

Thanks,

Roland
