Description
|
|
-----------
|
|
|
|
This driver implements support for ISA accesses *only* for
|
|
the Winbond W83627HF, W83627THF, W83697HF, W83637HF and W83687THF
|
|
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.
|
|
|
|
The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the
|
|
same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a
|
|
VID reading. However the two chips have the identical 128 pin package. So,
|
|
it is possible or even likely for a w83627thf to have the VID signals routed
|
|
to these pins despite their not being labeled for that purpose. Therefore,
|
|
the w83627thf driver interprets these as VID. If the VID on your board
|
|
doesn't work, first see doc/vid. If that still doesn't help, you may just
|
|
ignore the bogus VID reading with no harm done.
|
|
|
|
For further information on this driver, /proc values, etc.
|
|
see the w83781d driver documentation.
