+* Device tree bindings for TI TPS61050/61052 Boost Converters
+
+The TP61050/TPS61052 is a high-power "white LED driver". The
+device provides LED, GPIO and regulator functionalities.
+
+Required properties:
+- compatible:          "ti,tps61050" or "ti,tps61052"
+- reg:                 Specifies the I2C slave address
+
+Example:
+
+i2c0 {
+       tps61052@33 {
+               compatible = "ti,tps61052";
+               reg = <0x33>;
+       };
+};
