Goal of this patch series is to make the mc13892 PWRON1 button usable, found e.g. on amazon kindle D01100/D01200 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. V2: - 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/ (local) (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.
