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