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.
Example:
fan-max6650: max6650@1b {
reg = <0x1b>;
compatible = "maxim,max6650";
maxim,fan-microvolt = <12000000>;
maxim,fan-prescale = <4>;
};
