Subject: [PATCH v3 0/7] Fix, extend and support OF to mc13xxx pwrbutton

Goal of this patch series is to make the mc13892 PWRON1 button usable,
found e.g. on amazon kindle D01100/D01200/EY21 readers.
A ten-year-old IRQ issue needed a fix, mc13783-pwrbutton had to be
extended to the other to mc13xxx PMIC as well (keeping the mc13892
PWRON3 key unsupported for simplicity) and adding OF support.
The implementation has been tested on amazon kindle D01100 and D01200
readers using PWRON1 of a mc13892.

Changes in v3:
- Link to v2: https://lore.kernel.org/linux-input/20250823144441.12654-1-akurz@blala.de/
- Undo all changes to led-control (rename to fsl,led-control), thanks Rob
- Restructured the new buttons node for unevaluatedProperties: false
- Various other remarks from Rob
- Rebase to current state

Changes in v2:
- Link to v1: https://lore.kernel.org/linux-input/20250817102751.29709-1-akurz@blala.de/
- Convert dt-bindings from txt to fsl,mc13xxx.yaml and add vendor prefix
  to led-control property, causing changes in dts and driver.
- Change node name from pwrbuttons to buttons
- Change property debounce-delay-value to debounce-delay-ms
- Fixed a section mismatch error
- Fixed https://lore.kernel.org/r/202508210551.VzAtE5re-lkp@intel.com/
  (wrong index used when converting to array access)
- Usage of generic device properties API in mc13783-pwrbutton.c
- Provide chip-specific max button id via platform_device_id, therefore
  swap patches 3 and 4.
