    TI INA226 Bidirectional Current and Power Monitor.
    The <zephyr/dt-bindings/sensor/ina226.h> file should be included in the
    DeviceTree as it provides macros that can be used for initializing the
    configuration registers.

compatible: "ti,ina226"

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

properties:
  avg-count:
    type: int
    description: |
      Number of samples to average (applies to all inputs).
      Default is the power-on reset value.
    default: 1
    enum: [1, 4, 16, 64, 128, 256, 512, 1024]

  vbus-conversion-time-us:
    type: int
    description: |
      Vbus conversion time in microseconds.
      Default is the power-on reset value.
    default: 1100
    enum: [140, 204, 332, 588, 1100, 2116, 4156, 8244]

  vshunt-conversion-time-us:
    type: int
    description: |
      Vshunt conversion time in microseconds.
      Default is the power-on reset value.
    default: 1100
    enum: [140, 204, 332, 588, 1100, 2116, 4156, 8244]

  operating-mode:
    type: string
    description: |
      Selects mode of operation.
      Default is the power-on reset value.
    default: "Shunt and Bus, Continuous"
    enum:
      - "Power-Down (or Shutdown)"
      - "Shunt Voltage, Triggered"
      - "Bus Voltage, Triggered"
      - "Shunt and Bus, Triggered"
      - "Power-Down (or Shutdown)"
      - "Shunt Voltage, Continuous"
      - "Bus Voltage, Continuous"
      - "Shunt and Bus, Continuous"

  current-lsb-microamps:
    type: int
    required: true
    description: |
      Current LSB value in microAmpere.
      This value gives the measurement resolution for current measurement.
      Formula: current-lsb [μA] = maximum expected current [μA] / 2^15
      Higher resolution means lower range of current measurement, vice versa.

      For example, if maximum expected current is 15 [A]:
        then, current-lsb [μA] = 15000000 [μA] / 2^15 ~= 457.763 [μA].

      Note: rounded values may be used for convenience, e.g. 500uA/LSB.

  rshunt-micro-ohms:
    type: int
    required: true
    description: |
      Shunt resistor value in micro-ohms.
