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
|
