 1TPS65217 family of regulators
 2
 3The TPS65217 chip contains a boost converter and current sinks which can be
 4used to drive LEDs for use as backlights.

 6Required properties:
 7- compatible: "ti,tps65217"
 8- reg: I2C slave address
 9- backlight: node for specifying WLED1 and WLED2 lines in TPS65217
10- isel: selection bit, valid values: 1 for ISEL1 (low-level) and 2 for ISEL2 (high-level)
11- fdim: PWM dimming frequency, valid values: 100, 200, 500, 1000
12- default-brightness: valid values: 0-100
13
14Each regulator is defined using the standard binding for regulators.

18	tps: tps@24 {
19		reg = <0x24>;
20		compatible = "ti,tps65217";
21		backlight {
22			isel = <1>;  /* 1 - ISET1, 2 ISET2 */
23			fdim = <100>; /* TPS65217_BL_FDIM_100HZ */
24			default-brightness = <50>;
25		};
