+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.

+Generic devicetree bindings for onewire (w1) busses
+===================================================
+
+Onewire busses are described through nodes of their master bus controller.
+Slave devices are listed as sub-nodes of such master devices. For now, only
+one slave is allowed per bus master.
+
+
+Example:
+
+ charger: charger {
+ compatible = "gpio-charger";
+ charger-type = "mains";
+ gpios = <&gpio 1 GPIO_ACTIVE_LOW>;
+ };
+
+ onewire {
