[PATCH 0/3] Mediatek Genio EVKs: add MT6359 PMIC keys support

[Louis-Alexis Eyraud <louisalexis.eyraud@collabora.com>]

This patchset adds the support of the MT6359 PMIC keys (Power and Home)
that can be found on the Mediatek Genio 510, 700 and 1200 EVK boards
by:
- adding the MT6359 SoC support in the mtk-pmic-keys driver
- completing the existing definitions (only the Power key
  support was present) in Genio 510/700 EVK board common
  devicetree include file (mt8390-genio-common.dtsi)
- add the needed definitions in Genio 1200 EVK board devicetree
  (mt8395-genio-1200-evk.dts)

I've tested this patchset on Mediatek Genio 1200-EVK board with a
kernel based on linux-next (tag: next-20250703) plus [1] patch.
