Backlights are generally a subtype of LEDs at least from a software point of view if not always electrically. Move the bindings from the video directory to underneath the leds dir.

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>;
|
|
};
|
|
};
