description: ADLTC2990 Quad I2C Voltage, Current and Temperature Monitor

compatible: "adi,adltc2990"

include: [sensor-device.yaml, i2c-device.yaml]

properties:
  temperature-format:
    type: int
    description: |
      Define the temperature format. As per the datasheet,
      b7 Temperature Format Temperature Reported In; Celsius = 0 (Default), Kelvin = 1
    default: 0
    enum:
      - 0
      - 1

  acquistion-format:
    type: int
    description: |
      Define the acquisition format. As per the datasheet,
      b6 Repeat/Single Repeated Acquisition = 0 (Default), Single Acquisition = 1
    default: 0
    enum:
      - 0
      - 1

  measurement-mode:
    type: array
    description: |
      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:
      As per the datasheet,
      -------------------------------------------
      b[2:0] | Mode [2:0] | Mode Description
         0   |  0 0 0     | V1, V2, TR2 (Default)
         1   |  0 0 1     | V1 – V2, TR2
         2   |  0 1 0     | V1 – V2, V3, V4
         3   |  0 1 1     | TR1, V3, V4
         4   |  1 0 0     | TR1, V3 – V4
         5   |  1 0 1     | TR1, TR2
         6   |  1 1 0     | V1 – V2, V3 – V4
         7   |  1 1 1     | 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:
      As Per the Datasheet,
      ------------------------------------------------------------
      b[4:3] | Mode [4:3] | Mode Description
         0   |  0 0       | Internal Temperature Only (Default)
         1   |  0 1       | TR1, V1 or V1 – V2 Only per Mode [2:0]
         2   |  1 0       | TR2, V3 or V3 – V4 Only per Mode [2:0]
         3   |  1 1       | All Measurements per Mode [2:0]
      ------------------------------------------------------------
    default: [0, 0]
