-Bindings for a fan connected to the PWM lines
-
-Required properties:
-- compatible : "pwm-fan"
-- pwms : the PWM that is used to control the PWM fan
-- cooling-levels : PWM duty cycle values in a range from 0 to 255
- which correspond to thermal cooling states
-
-Example:
- fan0: pwm-fan {
- compatible = "pwm-fan";
- cooling-min-state = <0>;
- cooling-max-state = <3>;
- #cooling-cells = <2>;
- pwms = <&pwm 0 10000 0>;
- cooling-levels = <0 102 170 230>;
- };
-
- thermal-zones {
- cpu_thermal: cpu-thermal {
- thermal-sensors = <&tmu 0>;
- polling-delay-passive = <0>;
- polling-delay = <0>;
- trips {
- cpu_alert1: cpu-alert1 {
- temperature = <100000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };

- map0 {
