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