-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>;
- };
-};

The example was adapted in the following ways: - make use of the now supported 'function' and 'color' properties - remove pwm nodes, those are documented elsewhere - tweake node names to be matched by new dtschema rules License was discussed with the original author.
