Subject: [PATCH v6 0/3] 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 additional latencies between key change and
matrix scan.

This series applies on 6.14-rc4

* adapt dt-bindings description for gpio-activelow
* remove applied patches (https://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git/log/)

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
