Editing: leds-pwm.txt
LED connected to PWM Required properties: - compatible : should be "pwm-leds". Each LED is represented as a sub-node of the pwm-leds device. Each node's name represents the name of the corresponding LED. LED sub-node properties: - pwms : PWM property to point to the PWM device (phandle)/port (id) and to specify the period time to be used: <&phandle id period_ns>; - pwm-names : (optional) Name to be used by the PWM subsystem for the PWM device For the pwms and pwm-names property please refer to: Documentation/devicetree/bindings/pwm/pwm.txt - max-brightness : Maximum brightness possible for the LED - active-low : (optional) For PWMs where the LED is wired to supply rather than ground. - label : (optional) see Documentation/devicetree/bindings/leds/common.txt - linux,default-trigger : (optional) see Documentation/devicetree/bindings/leds/common.txt Example: twl_pwm: pwm { /* provides two PWMs (id 0, 1 for PWM1 and PWM2) */ compatible = "ti,twl6030-pwm"; #pwm-cells = <2>; }; twl_pwmled: pwmled { /* provides one PWM (id 0 for Charing indicator LED) */ compatible = "ti,twl6030-pwmled"; #pwm-cells = <2>; }; pwmleds { compatible = "pwm-leds"; kpad { label = "omap4::keypad"; pwms = <&twl_pwm 0 7812500>; max-brightness = <127>; }; charging { label = "omap4:green:chrg"; pwms = <&twl_pwmled 0 7812500>; max-brightness = <255>; }; };
