title: Freescale i.MX8MP DPI to LVDS bridge chip

maintainers:
  - Marek Vasut <marex@denx.de>

description: |
  The i.MX8MP mediamix contains two registers which are responsible
  for configuring the on-SoC DPI-to-LVDS serializer. This describes
  those registers as bridge within the DT.

properties:
  compatible:
    const: fsl,imx8mp-ldb

  clocks:
    maxItems: 1

  clock-names:
    const: ldb

  ports:
    $ref: /schemas/graph.yaml#/properties/ports

    properties:
      port@0:
        $ref: /schemas/graph.yaml#/properties/port
        description: Video port for DPI input.

      port@1:
        $ref: /schemas/graph.yaml#/properties/port
        description: Video port for LVDS Channel-A output (panel or bridge).

      port@2:
