Subject: [PATCH 0/6] Input: matrix-keypad: Various performance improvements
Date: Thu, 31 Oct 2024 07:29:58 +0100	[thread overview]
Message-ID: <20241031063004.69956-1-markus.burri@mt.com> (raw)

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
