+Generic simple phy device tree binding
+--------------------------------------
+
+A good number of phy implementations merely read dts properties,
+enable clocks, regulators or do resets without having a dedicated register
+map. This binding implements a generic phy driver which can be used for
+such simple implementations and avoid boilerplate code duplication.
+
+Required Properties:
+- compatible : must be "simple-phy"
+- phy-cells : must be 0
+
+Optional Properties:
+- bus-width : generic bus-width. Must be positive.
+- max-bitrate : generic max-bitrate. Must be positive.
+- pwr : phandle to phy pwr regulator node.
+
+Example:
+
+The following example is a can transceiver implemented as a generic phy.
+It has a max-bitrate property and a pwr regulator.
+
+
+transceiver1: can-transceiver {
+ compatible = "simple-phy";
+ max-bitrate = <5000000>;
+ pwr-supply = <&transceiver1_fixed>;
+ #phy-cells = <0>;
+};
