So you don't say that linux,keymap is required for twl4030-keypad (wasn't clear if you assumed that or not).

Which is why it could be optional in keymap-matrix.txt. I dont know anything about keymap/keypad's just asking the question?
It seems as if linux,keypad-no-autorepeat is intended to mean the same thing (if relevant to the device) across all drivers. Is that correct? If so it seems like moving it to be specified in a generic input binding makes sense, just not sure if keymap-matrix.txt is that place or not.
