<klh@google.com> received Sept. '04.
No changes by me other than include file path fixups.
Compiles, but will not insmod without i2c-core changes
or stubs to add xxx_nolock() functions.
-----------------
Here you go. I apologize for the fact this code is not integrated
into the lm_sensors package structure and thus will require you to
make various little updates. But I really wanted to get this out
before I'm yanked away again, and am pretty sure you can do it much
faster than I can figure out what needs to be done!
BTW the kernel files are built against 2.4.x where x varies; 18 and 19
should work.
Feel free to clean up anything.

* reading #VRDHOT inputs
* reading GPIO pins (input only for now)
* reading alarms status
* #PROCHOT override control
* #PROCHOT sampling interval control
* Manual PWM output control
* PWM output frequency control
Also, some whitespace cleanup in the driver.
