I'm sure I can figure it out. For example:
This adds experimental support for the it8603e chip found in the asus
f2a85-m motherboard.
Write only tested for pwmN and pwmN_enable.
Read tested, but the following appear broken:
alarms
fanN_alarm
inN_alarm
inN_max
inN_min
intrusionN_alarm
pwmN_auto_channels_temp
pwmN_freq
