+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: "mediatek,mt6397-keys" or "mediatek,mt6323-keys"
+- linux,keycodes: Specifies the numeric keycode values to
+	be used for reporting keys presses. The array can
+	contain up to 2 entries.
+
+Optional Properties:
+- wakeup-source: each key can be used as a wakeup source.
+- mediatek,long-press-mode: Long press key shutdown setting, 1 for
+	pwrkey only, 2 for pwrkey/homekey together, others for disabled.
+- debounce-interval: Long press key shutdown debouncing interval time
+	in seconds. 0/1/2/3 for 8/11/14/5 seconds. If not specified defaults to 0.
+
+Example:
+
+	pmic: mt6397 {
+		compatible = "mediatek,mt6397";
+
+		...
+
+		mt6397keys: mt6397keys {
+			compatible = "mediatek,mt6397-keys";
+			linux,keycodes = <KEY_POWER>, <KEY_VOLUMEDOWN>;
+			wakeup-source = <1>, <0>;
+			mediatek,long-press-mode = <1>;
+			debounce-interval = <0>;
+		};
+	};
