description:
  The SENINF CD-PHY is a set of CD-PHY connected to the SENINF CSI-2
  receivers. The number of PHYs depends on the SoC model.
  Depending on the SoC model, each PHYs can be either CD-PHY or D-PHY only
  capable.

properties:
  compatible:
    enum:
      - mediatek,mt8365-csi-rx

  reg:
    maxItems: 1

  num-lanes:
    enum: [2, 3, 4]

  '#phy-cells':
    enum: [0, 1]
    description: |
      If the PHY doesn't support mode selection then #phy-cells must be 0 and
      PHY mode is described using phy-type property.
      If the PHY supports mode selection, then #phy-cells must be 1 and mode
      is set in the PHY cells. Supported modes are:
        - PHY_TYPE_DPHY
        - PHY_TYPE_CPHY
      See include/dt-bindings/phy/phy.h for constants.

  phy-type:
    description:
      If the PHY doesn't support mode selection then this set the operating mode.
      See include/dt-bindings/phy/phy.h for constants.
