1 TPS65217 family of regulators 2 3 The TPS65217 chip contains a boost converter and current sinks which can be 4 used to drive LEDs for use as backlights. 5 6 Required properties: 7 - compatible: "ti,tps65217" 8 - reg: I2C slave address 9 - backlight: node for specifying WLED1 and WLED2 lines in TPS65217 10 - isel: selection bit, valid values: 1 for ISEL1 (low-level) and 2 for ISEL2 (high-level) 11 - fdim: PWM dimming frequency, valid values: 100, 200, 500, 1000 12 - default-brightness: valid values: 0-100 13 14 Each regulator is defined using the standard binding for regulators. 15 16 Example: 17 18 tps: tps@24 { 19 reg = <0x24>; 20 compatible = "ti,tps65217"; 21 backlight { 22 isel = <1>; /* 1 - ISET1, 2 ISET2 */ 23 fdim = <100>; /* TPS65217_BL_FDIM_100HZ */ 24 default-brightness = <50>; 25 }; 26 };
