| compatible: "microchip,tcn75a" |

| properties: |
| alert-gpios: |
| type: phandle-array |
| description: | |
| ALERT pin |
| This pin defaults to active low when produced by the sensor. |
| The property value should ensure the gpio flags properly describe |
| the signal that is presented to the driver. Required in order to use |
| triggering support. |
| |
| resolution: |
| type: string |
| default: "9-bit" |
| enum: |
| - "9-bit" |
| - "10-bit" |
| - "11-bit" |
| - "12-bit" |
| description: | |
| Sensor resolution. Higher resolutions will result in longer conversion |
| times. Note: datasheet's claim about the ambient temperature register: |
| > When the 0.5°C, 0.25°C or 0.125°C resolutions are selected, |
| > bit 6, bit 7 or bit 8 will remain clear <0>, |
| > respectively. |
| appears to be incorrect. Only conversion times seem to be affected by |
| resolution selection. |
| |
| oneshot-mode: |
| type: boolean |
| description: | |
| Oneshot sampling mode. Reduces power consumption, but disables triggering |
| feature as well as high resolution sampling. Only supported with 9 bit |
| resolution. |
