This series is needed to avoid key-loss if the GPIOs are connected via a
I2C GPIO MUX that introduces additional latencies between key change and
matrix scan.

This series applies on 6.13-rc6

Changes in V5:
* formatting and typo

Changes in V4:
* deprecate gpio-activelow in gpio-matrix-keypad.yaml
* change reference to linux,keymap in gpio-matrix-keypad.yaml

Changes in V3:
* fix 'references a file that doesn't exist' in wakeup-source.txt
* remove copied and deprecated properties from gpio-matrix-keypad.yaml
* extend patch description to clarify the changes
* rebase to 6.13-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
