good catch! That happens when one tries to mimic other drivers :/

I just checked all DT input drivers for autorepeat keyword:

DRIVER              CODE                        DOCUMENTATION
twl4030-keypad      linux,input-no-autorepeat   linux,keypad-no-autorepeat
omap4-keypad        linux,input-no-autorepeat   linux,keypad-no-autorepeat
samsung-keypad      linux,input-no-autorepeat   linux,keypad-no-autorepeat
stmpe-keypad        st,no-autorepeat            st,no-autorepeat
spear-keyboard      autorepeat                  autorepeat
tca8418-keypad      keypad,autorepeat           --- not documented ---
gpio-matrix-keypad  linux,no-autorepeat         linux,no-autorepeat
gpio-keys-polled    autorepeat                  autorepeat
gpio-keys           autorepeat                  --- no documentation ---

Any suggestions how to continue fixing this mess? I guess first of
all the documentation of omap4-keypad, samsung-keypad and of course
the new twl4030-keypad driver should be fixed.

Next it would be nice to choose one standard property name for this
and use it for twl4030-keypad. I suggest to use "linux,input-no-autorepeat".
