Update the docs accordingly.
Rename PWM registers so that it is clearer which chip uses them.
Remove outdated comments.
Fix the name in the w83627hf_driver structure.
Fix reserved register and PWM bits being written to on the W83627THF.

Description
|
|
-----------
|
|
|
|
This driver implements support for ISA accesses *only* for
|
|
the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
|
|
We will refer to them collectively as Winbond chips.
|
|
|
|
This driver supports ISA accesses, which should be more reliable
|
|
than i2c accesses. Also, for Tyan boards which contain both a
|
|
Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
|
|
using this driver will avoid i2c address conflicts and complex
|
|
initialization that were required in the w83781d driver
|
|
(lm_sensors releases 2.7.0 and earlier).
|
|
|
|
If you really want i2c accesses for these Super I/O chips,
|
|
use the w83781d driver. However this is not the preferred method
|
|
now that this ISA driver has been developed.
|
|
|
|
Technically, the w83627thf does not support a VID reading. However, it's
|
|
possible or even likely that your mainboard maker has routed these signals
|
|
to a specific set of general purpose IO pins (the Asus P4C800-E is one such
|
|
board). The w83627thf driver now interprets these as VID. If the VID on
|
|
your board doesn't work, first see doc/vid in the lm_sensors package. If
|
|
that still doesn't help, email us at sensors@stimpy.netroedge.com.
|
|
|
|
For further information on this driver, /proc values, etc.
|
|
see the w83781d driver documentation.
