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"; mediatek,long-press-mode = <1>; power-off-time-sec = <0>; power { linux,keycodes = <116>; wakeup-source; }; home { linux,keycodes = <114>; }; }; }; |
