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
- default-brightness: valid values: 0-100
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 */
default-brightness = <50>;
};
};
