properties:
  regulator-initial-mode:
      type: int
      description: |
        Initial operating mode of the regulator. Regulators modes can be
        used for better power saving, or different voltage configurations,
        and are hardware specific.
  regulator-allowed-modes:
      type: array
      description: |
        Array of operating modes that software may configure for the
        regulator at runtime. The set of possible operating modes depends on
        what the hardware supports.

  modesel-reg:
    type: int
    description: |
      Mode selection register. This register is used by the regulator driver
      to select the target mode of the regulator

  modesel-mask:
    type: int
    description: |
      Mode selection mask. Applied to a mode selection when it is written
      to the modesel-reg.

  properties:
      voltage-range:
          type: array
          required: true
          description: |
             array of voltage values in uV, followed by the register value that
             must be written to enable the voltage. For example, [3300000, 0x3]
             denotes a value of 0x3 must be written to the register to set 3.3V
      num-voltages:
          type: int
          required: true
          description: number of voltages present in the voltage-range array.

          required: true
          description: I2C register to write voltage selection value to
      vsel-mask:
          type: int
          required: true
          description: |
            Mask to apply to the voltage range value when written to vsel
            register
      enable-reg:
          type: int
          required: true
          description: I2C register to write enable value to
      enable-mask:
          type: int
          required: true
          description: |
            Mask to apply to the enable bit (either 1 for enabled,
            or 0 for disabled) when writing it to the I2C enable register.
      enable-val:
          type: int
          required: true
          description: |
            value to apply enable-mask to, and write to enable-reg in order
            to enable the regulator output.
      min-uV:
          type: int
          required: true

            to set a current limit of 800mA
      num-current-levels:
          type: int
          default: 0
