| 39 | Description |
| 40 | ----------- |
| 41 | |
| 42 | This driver implements support for several MAX6697 compatible temperature sensor |
| 43 | chips. The chips support one local temperature sensor plus four, six, or seven |
| 44 | remote temperature sensors. Remote temperature sensors are diode-connected |
| 45 | thermal transitors, except for MAX6698 which supports three diode-connected |
| 46 | thermal transistors plus three thermistors in addition to the local temperature |
| 47 | sensor. |
| 48 | |
| 49 | The driver provides the following sysfs attributes. temp1 is the local (chip) |
| 50 | temperature, temp[2..n] are remote temperatures. The actually supported |
| 51 | per-channel attributes are chip type and channel dependent. |
| 52 | |
| 53 | tempX_input RO temperature |
| 54 | tempX_max RW temperature maximum threshold |
| 55 | tempX_max_alarm RO temperature maximum threshold alarm |
| 56 | tempX_crit RW temperature critical threshold |
| 57 | tempX_crit_alarm RO temperature critical threshold alarm |
| 58 | tempX_fault RO temperature diode fault (remote sensors only) |
