10 - Jean Delvare <jdelvare@suse.com>
13 The ADT7473, ADT7475, ADT7476, and ADT7490 are thermal monitors and multiple
16 They support monitoring and controlling up to four fans (the ADT7490 can only
17 control up to three). They support reading a single on chip temperature
18 sensor and two off chip temperature sensors (the ADT7490 additionally
19 supports measuring up to three current external temperature sensors with
20 series resistance cancellation (SRC)).

28 Description taken from onsemiconductors specification sheets, with minor
44 Integer array, represents the active state of the pwm outputs If set to 0
45 the pwm uses a logic low output for 100% duty cycle. If set to 1 the pwm
46 uses a logic high output for 100% duty cycle.

55 "^adi,bypass-attenuator-in[0-4]$":
57 Configures bypassing the individual voltage input attenuator. If
58 set to 1 the attenuator is bypassed if set to 0 the attenuator is
59 not bypassed. If the property is absent then the attenuator
60 retains it's configuration from the bios/bootloader.
