+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 {
+ compatible = "w1-gpio";
+ gpios = <&gpio 100 0>, <&gpio 101 0>;
+
+ battery {
+ compatible = "maxim,ds2760";
+ power-supplies = <&charger>;
+ };
+ };
