At the moment a programmer wishing to use the lm_sensors package needs to know
what chips are supported and needs to add all those chips into his package.
If you were to add a field or function to your structures to the effect of
sensor-function a programmer could use the package a lot more simply.
For values you could do something like -
enum sensor-type { volt, fan, temp, volt_min, volt_max, fan_div, fan_min,
temp_over, temp_hyst }
and I wouldn't mind betting that at some point in the future somebody decides
to put in sensors for amperage and humidity.
Anyway with this field you would not need to know what sensors belong to what
chip.
It seems that at the moment a /etc/sensors.conf file needs to have "default
labels" in it for all the user programs to work and if your chip is "none
standard" then your users have no idea of what is actually hapening.
I brought this problem up because my mortarboard (elite k7s5a) uses a sis735
driven by i2c-sis645 and does not give standard values (according to how I read
your docs).
After a lot of rebooting and comparing to my bios values i got a sensor dump of
this
