| Bindings for MAX6651 and MAX6650 I2C fan controllers
|
| Reference:
| [1] https://datasheets.maximintegrated.com/en/ds/MAX6650-MAX6651.pdf
|
| Required properties:
| - compatible : One of "maxim,max6650" or "maxim,max6651"
| - reg : I2C address, one of 0x1b, 0x1f, 0x4b, 0x48.
|
| Optional properties, default is to retain the chip's current setting:
| - maxim,fan-microvolt : The supply voltage of the fan, either 5000000 uV or
| 12000000 uV.
| - maxim,fan-prescale : Pre-scaling value, as per datasheet [1]. Lower values
| allow more fine-grained control of slower fans.
| Valid: 1, 2, 4, 8, 16.
| - maxim,fan-target-rpm: Initial requested fan rotation speed. If specified, the
| driver selects closed-loop mode and the requested speed.
| This ensures the fan is already running before userspace
| takes over.
|
| Example:
| fan-max6650: max6650@1b {
| reg = <0x1b>;
| compatible = "maxim,max6650";
| maxim,fan-microvolt = <12000000>;
| maxim,fan-prescale = <4>;
| maxim,fan-target-rpm = <1200>;
| };
