+Qualcomm PON Device
+
+The Power On device for Qualcomm PM8xxx is MFD supporting pwrkey
+and resin along with the Android reboot-mode.
+
+This DT node has pwrkey and resin as sub nodes.
+
+Required Properties:
+-compatible: "qcom,pm8916-pon"
+-reg: Specifies the physical address of the pon register
+
+Optional subnode:
+-pwrkey: Specifies the subnode pwrkey and should follow the
+ qcom,pm8941-pwrkey.txt description.
+-resin: Specifies the subnode resin and should follow the
+ qcom,pm8xxx-pwrkey.txt description.
+
+The rest of the properties should follow the generic reboot-mode description
+found in reboot-mode.txt
+
+Example:
+
+	pon@800 {
+		compatible = "qcom,pm8916-pon";
+
+		reg = <0x800>;
+		mode-bootloader = <0x2>;
+		mode-recovery = <0x1>;
+
+		pwrkey {
+			compatible = "qcom,pm8941-pwrkey";
+			interrupts = <0x0 0x8 0 IRQ_TYPE_EDGE_BOTH>;
+			debounce = <15625>;
+			bias-pull-up;
+			linux,code = <KEY_POWER>;
+		};
+
+		resin {
+			compatible = "qcom,pm8941-resin";
+			interrupts = <0x0 0x8 1 IRQ_TYPE_EDGE_BOTH>;
+			debounce = <15625>;
+			bias-pull-up;
+			linux,code = <KEY_VOLUMEDOWN>;
+		};

+Devicetree bindings for Maxim DS2760
+====================================
+
+The ds2760 is a w1 slave device and must hence have its sub-node in DT
+under a w1 bus master node.
+
+The device exposes a power supply, so the details described in
+Documentation/devicetree/bindings/power/supply/power_supply.txt apply.
+
+Required properties:
+- compatible: must be "maxim,ds2760"
+
+Optional properties:
+- power-supplies:	Refers to one or more power supplies connected to
+			this battery.
+- maxim,pmod-enabled:	This boolean property enables the DS2760 to enter
+			sleep mode when the DQ line goes low for greater
+			than 2 seconds and leave sleep Mode when the DQ
+			line goes high.
+- maxim,cache-time-ms:	Time im milliseconds to cache the data for. When
+			this time expires, the values are read again from
+			the hardware. Defaults to 1000.
+- rated-capacity-microamp-hours:
+			The rated capacity of the battery, in mAh.
+			If not specified, the value stored in the
+			non-volatile chip memory is used.
