-MediaTek MT6397/MT6323 PMIC Keys Device Driver
-
-There are two key functions provided by MT6397/MT6323 PMIC, pwrkey
-and homekey. The key functions are defined as the subnode of the function
-node provided by MT6397/MT6323 PMIC that is being defined as one kind
-of Muti-Function Device (MFD)
-
-For MT6397/MT6323 MFD bindings see:
-Documentation/devicetree/bindings/mfd/mt6397.txt
-
-Required properties:
-- compatible: Should be one of:
- - "mediatek,mt6397-keys"
- - "mediatek,mt6323-keys"
- - "mediatek,mt6358-keys"
-- linux,keycodes: See Documentation/devicetree/bindings/input/input.yaml
-
-Optional Properties:
-- wakeup-source: See Documentation/devicetree/bindings/power/wakeup-source.txt
-- mediatek,long-press-mode: Long press key shutdown setting, 1 for
- pwrkey only, 2 for pwrkey/homekey together, others for disabled.
-- power-off-time-sec: See Documentation/devicetree/bindings/input/input.yaml
-
-Example:
-
- pmic: mt6397 {
- compatible = "mediatek,mt6397";
-
- ...
-
- mt6397keys: mt6397keys {
- compatible = "mediatek,mt6397-keys";

- power-off-time-sec = <0>;

- wakeup-source;
- };
-
- home {
- linux,keycodes = <114>;
- };
- };

Convert the mtk-pmic-keys to DT schema format. The old binding was missing documentation for key press/release interrupts, even though it was supported in hardware and driver, so support for the same was added during the conversion.
