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>; |
|
}; |
|
}; |
