| ltc2990: Linear Technology LTC2990 power monitor |
| |
| Required properties: |
| - compatible: Must be "lltc,ltc2990" |
| - reg: I2C slave address |
| - lltc,meas-mode: |
| An array of two integers for configuring the chip measurement mode. |
| |
| The first integer defines the bits 2..0 in the control register. In all |
| cases the internal temperature and supply voltage are measured. In |
| addition the following input measurements are enabled per mode: |
| |
| 0: V1, V2, TR2 |
| 1: V1-V2, TR2 |
| 2: V1-V2, V3, V4 |
| 3: TR1, V3, V4 |
| 4: TR1, V3-V4 |
| 5: TR1, TR2 |
| 6: V1-V2, V3-V4 |
| 7: V1, V2, V3, V4 |
| |
| The second integer defines the bits 4..3 in the control register. This |
| allows a subset of the measurements to be enabled: |
| |
| 0: Internal temperature and supply voltage only |
| 1: TR1, V1 or V1-V2 only per mode |
| 2: TR2, V3 or V3-V4 only per mode |
| 3: All measurements per mode |
| |
| Example: |
| |
| ltc2990@4c { |
| compatible = "lltc,ltc2990"; |
| reg = <0x4c>; |
| lltc,meas-mode = <7 3>; /* V1, V2, V3, V4 */ |
| }; |
