| 70 | Description | |
| 71 | ----------- | |
| 72 | ||
| 73 | This driver implements support for several MAX6697 compatible temperature sensor | |
| 74 | chips. The chips support one local temperature sensor plus four, six, or seven | |
| 75 | remote temperature sensors. Remote temperature sensors are diode-connected | |
| 12087a36 | 76 | thermal transistors, except for MAX6698 which supports three diode-connected |
| 5372d2d7 GR |
77 | thermal transistors plus three thermistors in addition to the local temperature |
| 78 | sensor. | |
| 79 | ||
| 80 | The driver provides the following sysfs attributes. temp1 is the local (chip) | |
| 81 | temperature, temp[2..n] are remote temperatures. The actually supported | |
| 82 | per-channel attributes are chip type and channel dependent. | |
