| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Must be "lltc,ltc2990" |
| 5 | - reg: I2C slave address |
| 6 | - lltc,meas-mode: |
| 7 | An array of two integers for configuring the chip measurement mode. |
| 8 | |
| 9 | The first integer defines the bits 2..0 in the control register. In all |
| 10 | cases the internal temperature and supply voltage are measured. In |
| 11 | addition the following input measurements are enabled per mode: |
| 12 | |
| 13 | 0: V1, V2, TR2 |
| 14 | 1: V1-V2, TR2 |
| 15 | 2: V1-V2, V3, V4 |
| 16 | 3: TR1, V3, V4 |
| 17 | 4: TR1, V3-V4 |
| 18 | 5: TR1, TR2 |
| 19 | 6: V1-V2, V3-V4 |
| 20 | 7: V1, V2, V3, V4 |
| 21 | |
| 22 | The second integer defines the bits 4..3 in the control register. This |
| 23 | allows a subset of the measurements to be enabled: |
| 24 | |
| 25 | 0: Internal temperature and supply voltage only |
| 26 | 1: TR1, V1 or V1-V2 only per mode |
| 27 | 2: TR2, V3 or V3-V4 only per mode |
| 28 | 3: All measurements per mode |
| 29 | |
| 30 | Example: |
| 31 | |
| 32 | ltc2990@4c { |
| 33 | compatible = "lltc,ltc2990"; |
| 34 | reg = <0x4c>; |
| 35 | lltc,meas-mode = <7 3>; /* V1, V2, V3, V4 */ |
| 36 | }; |
