-* Dialog DA9061/62/63 OnKey Module
-
-This module is part of the DA9061/DA9062/DA9063. For more details about entire
-DA9062 and DA9061 chips see Documentation/devicetree/bindings/mfd/da9062.txt
-For DA9063 see Documentation/devicetree/bindings/mfd/dlg,da9063.yaml
-
-This module provides the KEY_POWER event.
-
-Required properties:
-
-- compatible: should be one of the following valid compatible string lines:
-	"dlg,da9061-onkey", "dlg,da9062-onkey"
-	"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 when triggered using a long press of the OnKey.
-
-Example: DA9063
-
-	pmic0: da9063@58 {
-		onkey {
-			compatible = "dlg,da9063-onkey";
-			dlg,disable-key-power;
-		};
-	};

-Example: DA9062
-
-	pmic0: da9062@58 {
-		onkey {
-			compatible = "dlg,da9062-onkey";
-			dlg,disable-key-power;
-		};
-	};
-
-Example: DA9061 using a fall-back compatible for the DA9062 onkey driver
-
-	pmic0: da9061@58 {
-		onkey {
-			compatible = "dlg,da9061-onkey", "dlg,da9062-onkey";
-			dlg,disable-key-power;
-		};
