1 GMT G762/G763 PWM Fan controller
3 Required node properties:
5 - "compatible": must be either "gmt,g762" or "gmt,g763"
6 - "reg": I2C bus address of the device
7 - "clocks": a fixed clock providing input clock frequency
8 on CLK pin of the chip.
12 - "fan_startv": fan startup voltage. Accepted values are 0, 1, 2 and 3.
15 - "pwm_polarity": pwm polarity. Accepted values are 0 (positive duty)
16 and 1 (negative duty).
18 - "fan_gear_mode": fan gear mode. Supported values are 0, 1 and 2.
20 If an optional property is not set in .dts file, then current value is kept
21 unmodified (e.g. u-boot installed value).
23 Additional information on operational parameters for the device is available
24 in Documentation/hwmon/g762.rst. A detailed datasheet for the device is available
25 at http://natisbad.org/NAS/refs/GMT_EDS-762_763-080710-0.2.pdf.
