* Dialog's onkey device tree bindings

The da9063 onkey driver allow for the user space handling of power events
like suspend to RAM or poweroff.

Required properties:

- compatible: Must be "dlg,da9063-onkey".
- interrupts: Local Da9063 interrupt line.
- interrupt-name: Local DA9063 interrupt line name.

Optional properties:
- dlg,key-power: Indicates the power key is enabled in OTP.

Example:

	onkey {
		compatible = "dlg,da9063-onkey";
		interrupts = <0>;
		interrupts-names = "ONKEY";
		interrupt-parent = <&pmic_dialog>;
		dlg,key-power;
	};
