+TPS65217 family of regulators
+
+The TPS65217 chip contains a boost converter and current sinks which can be
+used to drive LEDs for use as backlights.
+
+Required properties:
+- compatible: "ti,tps65217"
+- reg: I2C slave address
+- backlight: node for specifying WLED1 and WLED2 lines in TPS65217
+- isel: selection bit, valid values: 1 for ISEL1 (low-level) and 2 for ISEL2 (high-level)
+- fdim: PWM dimming frequency, valid values: 100, 200, 500, 1000
+
+Each regulator is defined using the standard binding for regulators.
+
+Example:
+
+ tps: tps@24 {
+ reg = <0x24>;
+ compatible = "ti,tps65217";
+ backlight {
+ isel = <1>; /* 1 - ISET1, 2 ISET2 */
+ fdim = <100>; /* TPS65217_BL_FDIM_100HZ */
+ };
+ };
