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 and adding OF support. The implementation has been tested only with PWRON1 on an mc13892. Changes in v4: - Link to v3: https://lore.kernel.org/linux-input/20250829201517.15374-1-akurz@xxxxxxxx/ - Rebase to git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd.git tags/ib-mfd-input-rtc-v6.18 in order to include a different mc13xxx related patch (sorry for that). - Re-ordered commits since dt-bindings changes already go reviewes by Rob Herring. - Following Dmitrys suggestions, resources for irq are now passed from mfd to input allowing a more simple implementation. Work on other mfd cells with irq usage might still be a future project. - Input-related differences between the mc13xxx variants are encoded in data structures, making the implementation of mc13892 PWRON3 a simple task. Changes in v3: - Link to v2: https://lore.kernel.org/linux-input/20250823144441.12654-1-akurz@xxxxxxxx/ - 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@xxxxxxxx/ - 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@xxxxxxxxx/ (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.
