The device supports:\n+ - One internal sensor\n+ - Four external I2C digital sensors\n+ - Six external thermal diodes\n+\n+Optional properties:\n+- use-stored-presence : Do not treat the devicetree description as canon for\n+ fan presence (the 'installed' bit of FAN_CONFIG_*).\n+ Instead, rely on the on the default value store of\n+ the device to populate it.\n+\n+Capabilities are configured through subnodes of the controller's node.\n+\n+Fans\n+----\n+\n+Only fans with subnodes present will be considered as installed. If\n+use-stored-presence is present in the parent node, then only fans that are both\n+defined in the devicetree and have their installed bit set are considered\n+installed.\n+\n+Required subnode properties:\n+- compatible : Must be \"pmbus-fan\"\n+- reg : The PMBus page the properties apply to.\n+- #cooling-cells : Should be 2. See the thermal bindings at [1].\n+- maxim,fan-rotor-input : The type of rotor measurement provided to the\n+ controller. Must be either \"tach\" for tachometer\n+ pulses or \"lock\" for a locked-rotor signal.\n+- maxim,fan-lock-polarity: Required iff maxim,fan-rotor-input is \"lock\". Valid\n+ values are \"low\" for active low, \"high\" for active\n+ high.\n+\n+Optional subnode properties:\n+- fan-mode : \"rpm\" or \"pwm\". Default value is \"pwm\".\n+- tach-pulses : Tachometer pulses per revolution. Valid values are\n+ 1, 2, 3 or 4. The default is 1.\n+- cooling-min-level : Smallest cooling state accepted. See [1].\n+- cooling-max-level : Largest cooling state accepted. See [1].\n+- maxim,fan-no-fault-ramp: Do not ramp the fan to 100% PWM duty on detecting a\n+ fan fault\n+- maxim,fan-startup : The number of rotations required before taking\n+ emergency action for an unresponsive fan and driving\n+ it with 100% or 0% PWM duty, depending on the state\n+ of maxim,fan-no-fault-ramp. Valid values are 0\n+ (automatic spin-up disabled), 2, 4, or 8. Default\n+ value is 0.\n+- maxim,fan-health : Enable automated fan health check\n+- maxim,fan-ramp : Configures how fast the device ramps the PWM duty\n+ cycle from one value to another. Valid values are 0\n+ to 7 inclusive, with values 0 - 2 configuring a\n+ 1000ms update rate and 1 - 3% duty respective duty\n+ increase, and 3 - 7 a 200ms update rate with a 1 -\n+ 5% respective duty increase. Default value is 0.\n+- maxim,fan-no-watchdog : Do not ramp fan to 100% PWM duty on failure to\n+ update desired fan rate inside 10s. This implies\n+ maxim,tmp-no-fault-ramp\n+- maxim,tmp-no-fault-ramp: Do not ramp fan to 100% PWM duty on temperature\n+ sensor fault detection. This implies\n+ maxim,fan-no-watchdog\n+- maxim,tmp-hysteresis : The temperature hysteresis used to determine\n+ transitions to lower fan speed bands in the\n+ temperature/fan rate lookup table. Valid values are\n+ 2, 4, 6 or 8 (degrees celcius). Default value is 2.\n+- maxim,fan-dual-tach : Enable dual tachometer functionality\n+- maxim,fan-pwm-freq : The PWM frequency. Valid values are 30, 50, 100, 150\n+ and 25000 (Hz). Default value is 30Hz.\n+- maxim,fan-lookup-table : A 16-element cell array of alternating temperature\n+ and rate values representing the look up table. The\n+ rate units are set through the fan-mode property.\n+- maxim,fan-fault-pin-mon: Ramp fans to 100% PWM duty when the FAULT pin is\n+ asserted\n+\n+Temperature\n+-----------\n+\n+Required subnode properties:\n+- compatible : Must be \"pmbus-temperature\"\n+- reg : The PMBus page the properties apply to.\n+\n+Optional subnode properties:\n+- maxim,tmp-offset : Valid values are 0 - 30 (degrees celcius) inclusive.\n+ Default value is 0.\n+- maxim,tmp-fans : An array of phandles to fans controlled by the\n+ current temperature sensor.\n+\n+[1] Documentation/devicetree/bindings/thermal/thermal.txt\n+\n+Example:\n+\tfan-max31785: max31785@52 {\n+\t\treg = <0x52>;\n+\t\tcompatible = \"maxim,max31785\";\n+ #address-cells = <1>;\n+ #size-cells = <0>;\n+ #thermal-sensor-cells = <1>;\n+\n+ fan@0 {\n+ compatible = \"pmbus-fan\";\n+ reg = <0>;\n+ mode = \"rpm\";\n+ tach-pulses = <1>;\n+\n+ #cooling-cells = <2>;\n+ cooling-min-level = <0>;\n+ cooling-max-level = <9>;\n+\n+ maxim,fan-rotor-input = \"tach\";\n+ maxim,fan-dual-tach;\n+ };\n+\n+ /*\n+ * Hardware controlled fan: Fan speed is controlled by a\n+ * temperature sensor feeding values into the lookup table.
