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>; }; };
