* Dialog DA9062/63 OnKey Module
This module is part of the DA9062/DA9063. For more details about entire
chips see Documentation/devicetree/bindings/mfd/da9062.txt and
Documentation/devicetree/bindings/mfd/da9063.txt
This module provides KEY_POWER, KEY_SLEEP and events.
Required properties:
- compatible: should be one of:
dlg,da9062-onkey
dlg,da9063-onkey
Optional properties:
- dlg,disable-key-power : Disable power-down using a long key-press. If this
entry exists the OnKey driver will remove support for the KEY_POWER key
press. If this entry does not exist then by default the key-press
triggered power down is enabled and the OnKey will support both KEY_POWER
and KEY_SLEEP.
Example:
pmic0: da9062@58 {
onkey {
compatible = "dlg,da9063-onkey";
dlg,disable-key-power;
};
};
