+TPS611xx family of backlight driver based on EasyScale.
+
+EasyScale is a simple but flexible one pin interface to configure the current.
+
+Required properties:
+- compatible: should contain at least one of
+ "ti,tps61158_bl"
+ "ti,tps61161_bl"
+ "ti,tps61163_bl"
+ "ti,tps61165_bl"
+- rfa-enable: enable request for acknowledge.
+ If RFA is enabled, the data byte includes the RFA bit and device will wait
+ and check acknowledge from device.
+- es-gpio : GPIO for easy-scale communication.(see GPIO binding[0])
+
+[0]: Documentation/devicetree/bindings/gpio/gpio.txt
+
+Example:
+
+ backlight {
+ compatible = "ti,tps61163";
+ rfa-enable;
+ es-gpio = <&gpio 45 0>;
+ };
