As promised:

This patch adds ST Keyscan driver to use the keypad hw a subset
of ST boards provide. Specific board setup will be put in the
given dt.

Are you sure these are in the correct order?

ok i change the order

+- linux,keymap: The keymap for keys as described in the binding document

+- keypad,num-rows: Number of row lines connected to the keypad controller.

+- keypad,num-columns: Number of column lines connected to the keypad
+  controller.
+
+- st,debounce_us: Debouncing interval time in microseconds

I'm sure there will be a shared binding for de-bounce.

If not, there certainly should be.

you want to refer to "debounce-interval" ?

Is there any way we can make this more specific to _this_ IP?

for my knowledge this IP is the same for stixxxx platform.
