This series is needed to avoid key-loss if the GPIOs are connected via a I2C GPIO Mux
that introduces additonal latencies between key change and matrix scan.
Patch 1, 2 and 6 in this series introduce a performance boost on its own
and can be merged separately.
Patch 3, 4 and 5 depend on each other.
Markus Burri (6):
Input: matrix_keypad - move gpio-row init to the init part
Input: matrix_keypad - use fsleep for variable delay duration
Input: matrix_keypad - add function for reading row state
dt-bindings: input: matrix_keypad - add settle time after enable all
columns
Input: matrix_keypad - add settle time after enable all columns
Input: matrix_keypad - detect change during scan
