[lm-sensors] hwmon/pc87360 as a platform driver

[jim.cromie@gmail.com (Jim Cromie)]

hi folks,

Ive just made a rough pass thru pc87360, and have converted it
to a non-working, but non-crashing platform_driver that does
at least a little of what it should:

soekris:~# modprobe pc87360
[  964.952000] pc87360: Device 0x09 not activated
[  966.576000] pc87360 pc87360.26144: VLM conversion set to 1s period, 
160us delay

so far so good, but:

soekris:~# sensors -s
No sensors found!

my libsensors is unstable debian package:  libsensors 1:2.10.0-3
That version number looks to contain 2.10.0

Frankly, Im hoping that with 2.10, the user-side just works, but this is 
not the case here.

Any guesses / suggestions as to whats wrong ?
Im continuiing to look at the kernel-side (Im sure Ive got multiple errs 
in there)
Im hoping for some user-side-fu for free ;-)


for anyone reading along, this is a perfect ref:
    
http://lists.lm-sensors.org/pipermail/lm-sensors/2006-February/015180.html

given the wider staging issues, this is arguably a later/lower priority.
