dt-bindings: leds: backlight: Convert TPS65217 to DT schema
Convert the Texas Instruments TPS65217 bindings to DT schema. During the conversion, the following updates were made: - Documented the 'regulators', 'charger' and 'pwrbutton' child nodes, which are used by the boards but were missing from the old txt binding. - Documented the 'interrupts', 'interrupt-controller', '#interrupt-cells' and 'ti,pmic-shutdown-controller' properties, which are used by the am335x boards and read by the driver. The regulator/tps65217.txt binding documented the same 'ti,tps65217' compatible and is superseded by this schema, so remove it as well.

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";
