|  | 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>; | 
|  | }; | 
|  | }; |
