-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
-
-Optional properties:
-- fan-supply : phandle to the regulator that provides power to the fan
-- interrupts : This contains a single interrupt specifier which
- describes the tachometer output of the fan as an
- interrupt source. The output signal must generate a
- defined number of interrupts per fan revolution, which
- require that it must be self resetting edge interrupts.
- See interrupt-controller/interrupts.txt for the format.
-- pulses-per-revolution : define the tachometer pulses per fan revolution as
- an integer (default is 2 interrupts per revolution).
- The value must be greater than zero.
-
-Example:
- fan0: pwm-fan {
- compatible = "pwm-fan";
- #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";
- };
- };
- cooling-maps {
- map0 {
- trip = <&cpu_alert1>;
- cooling-device = <&fan0 0 1>;
- };
- };
- };
-
-Example 2:
- fan0: pwm-fan {
- compatible = "pwm-fan";
- pwms = <&pwm 0 40000 0>;
- fan-supply = <&reg_fan>;
- interrupt-parent = <&gpio5>;
- interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
- pulses-per-revolution = <2>;
- };
