Subject: [PATCH v2 0/7] Input: matrix-keypad: Various performance improvements

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.

This series applies on 6.12-rc6

Changes in V2:
* added patch to convert dt-bindings to YAML
* added missing dt-bindings properties description
* removed [PATCH 1/6] Input: matrix_keypad - move gpio-row init to the init
  it would revert 01c84b03d80aab9f04c4e3e1f9085f4202ff7c29
* removed internally given Tested-by and Reviewed-by tags
