+* 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;
+ };
+
+ };

+- rotary-encoder,steps-per-period: Number of steps (stable states) per period.
+ The values have the following meaning:
