w83627ehf - Driver for the hardware monitoring functionality of
the Winbond W83627EHF Super-I/O chip

Shamelessly ripped from the w83627hf driver
Copyright (C) 2003 Mark Studebaker
Supports the following chips:
- Chip #vin #fan #pwm #temp chip_id man_id
- w83627ehf - 5 - 3 0x88 0x5ca3
-
- This is a preliminary version of the driver, only supporting the
- fan and temperature inputs. The chip does much more than that.
