| 18 | Optional properties: | |
| 19 | ||
| 20 | - smbus-timeout-disable | |
| 21 | Set to disable SMBus timeout. If not specified, SMBus timeout will be | |
| 22 | enabled. | |
| 23 | - extended-range-enable | |
| 24 | Only valid for MAX6581. Set to enable extended temperature range. | |
| 25 | Extended temperature will be disabled if not specified. | |
| 26 | - beta-compensation-enable | |
| 27 | Only valid for MAX6693 and MX6694. Set to enable beta compensation on | |
| 28 | remote temperature channel 1. | |
| 29 | Beta compensation will be disabled if not specified. | |
| 30 | - alert-mask | |
| 31 | Alert bit mask. Alert disabled for bits set. | |
| 32 | Select bit 0 for local temperature, bit 1..7 for remote temperatures. | |
| 33 | If not specified, alert will be enabled for all channels. | |
| 34 | - over-temperature-mask | |
| 35 | Over-temperature bit mask. Over-temperature reporting disabled for | |
| 36 | bits set. | |
| 37 | Select bit 0 for local temperature, bit 1..7 for remote temperatures. | |
| 38 | If not specified, over-temperature reporting will be enabled for all | |
| 39 | channels. | |
| 40 | - resistance-cancellation | |
| 41 | Boolean for all chips other than MAX6581. Set to enable resistance | |
| 42 | cancellation on remote temperature channel 1. | |
| 43 | For MAX6581, resistance cancellation enabled for all channels if | |
| 44 | specified as boolean, otherwise as per bit mask specified. | |
| 45 | Only supported for remote temperatures (bit 1..7). | |
| 46 | If not specified, resistance cancellation will be disabled for all | |
| 47 | channels. | |
| 48 | - transistor-ideality | |
| 49 | For MAX6581 only. Two values; first is bit mask, second is ideality | |
| 50 | select value as per MAX6581 data sheet. Select bit 1..7 for remote | |
| 51 | channels. | |
| 52 | Transistor ideality will be initialized to default (1.008) if not | |
| 53 | specified. | |

| 59 | reg = <0x1a>; | |
| 60 | smbus-timeout-disable; | |
| 61 | resistance-cancellation; | |
| 62 | alert-mask = <0x72>; | |
| 63 | over-temperature-mask = <0x7f>; | |
| 64 | }; |
