1 TPS65217 family of regulators
2
3 The TPS65217 chip contains a boost converter and current sinks which can be
4 used to drive LEDs for use as backlights.
5
6 Required 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
14 Each regulator is defined using the standard binding for regulators.

16 Example:
17
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 };
26 };
