Hi all,
Here's a rough first cut at converting the adm1021.c driver over to
sysfs. The second driver in, and already we're violating the published
documentation :)
There's a die_code value that isn't in the docs, and I have no idea how
to handle the *prec variables that can be read from a adm1023 chip.
Also, I'm pretty sure the write logic is wrong, and the scale of the
read values is also incorrect, but as I don't have this hardware, I
would really appreciate any fixes for this patch.
The patch should apply cleanly to 2.5.66 and any later -bk trees.
thanks,
greg k-h
