[PATCH v4 00/19] Get mt6359-accdet ready for usage in Devicetree

["Nícolas F. R. A. Prado" <nfraprado@collabora.com>]

This series prepares the MT6359 ACCDET for actual usage in the
Devicetree. Patch 1 adds the required DT bindings, patches 2 and 3 get
the mt6359-accdet driver probing, patches 4-17 clean up code related to
DT property parsing, patch 18 adds the node in the Devicetree and patch
19 enables the kconfig for the driver.

Together with the series "Allow retrieving accessory detection reference
on MT8188" [1], and one extra patch on top enabling it on the
genio-700-evk DT, this series was tested on the Genio 700 EVK to get
audio jack detection working on it.

Changes in v4:
- Moved DT-binding for accdet from standalone file
  (sound/mediatek,mt6359-accdet.yaml) to parent mfd's file
  (mfd/mediatek,mt6397.yaml), squashing patches 1 and 2.
- Link to v3: https://lore.kernel.org/r/20250304-mt6359-accdet-dts-v3-0-5b0eafc29f5b@collabora.com

Changes in v3:
- Removed unneeded '|' in mt6359-accdet's dt-binding description
- Removed unneeded unevaluatedProperties for accdet node in mt6397's
  dt-binding
- Clarified HP_EINT pin is on the MT6359 PMIC in mediatek,hp-eint-high's
  description in the mt6359-accdet dt-binding
- Link to v2: https://lore.kernel.org/r/20250302-mt6359-accdet-dts-v2-0-5bd633ee0d47@collabora.com

Changes in v2:
- Removed all DT-binding properties except for EINT polarity one
  (mediatek,eint-level-pol / mediatek,hp-eint-high)
  - Added patches 12-18 to make those settings internal to driver
- Renamed mediatek,eint-level-pol to mediatek,hp-eint-high and made it
  bool
- Added patch 20 to enable the MT6359 ACCDET Kconfig in the defconfig
- Removed unused btn_type variable as part of "Drop dead code for button
  detection" patch.
