| 69 | Description |
|---|
| 70 | ----------- |
|---|
| 71 | |
|---|
| 72 | This driver implements support for ISA accesses *only* for |
|---|
| 73 | the Winbond W83627HF, W83627THF, W83697HF, W83637HF and W83687THF |
|---|
| 74 | Super I/O chips. We will refer to them collectively as Winbond chips. |
|---|
| 75 | |
|---|
| 76 | This driver supports ISA accesses, which should be more reliable |
|---|
| 77 | than i2c accesses. Also, for Tyan boards which contain both a |
|---|
| 78 | Super I/O chip and a second i2c-only Winbond chip (often a W83782D), |
|---|
| 79 | using this driver will avoid i2c address conflicts and complex |
|---|
| 80 | initialization that were required in the w83781d driver |
|---|
| 81 | (lm_sensors releases 2.7.0 and earlier). |
|---|
| 82 | |
|---|
| 83 | If you really want i2c accesses for these Super I/O chips, |
|---|
| 84 | use the w83781d driver. However this is not the preferred method |
|---|
| 85 | now that this ISA driver has been developed. |
|---|
| 86 | |
|---|
| 87 | The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the |
|---|
| 88 | same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a |
|---|
| 89 | VID reading. However the two chips have the identical 128 pin package. So, |
|---|
| 90 | it is possible or even likely for a w83627thf to have the VID signals routed |
|---|
| 91 | to these pins despite their not being labeled for that purpose. Therefore, |
|---|
| 92 | the w83627thf driver interprets these as VID. If the VID on your board |
|---|
| 93 | doesn't work, first see doc/vid. If that still doesn't help, you may just |
|---|
| 94 | ignore the bogus VID reading with no harm done. |
|---|
| 95 | |
|---|
| 96 | For further information on this driver, /proc values, etc. |
|---|
| 97 | see the w83781d driver documentation. |
