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:
    enum:
      - fsl,imx6sx-ldb
      - fsl,imx8mp-ldb
      - fsl,imx93-ldb

  clocks:
    maxItems: 1

  clock-names:
    const: ldb

  reg:
    maxItems: 2

  reg-names:
    items:
      - const: ldb
      - const: lvds

  nxp,enable-termination-resistor:
    type: boolean
    description:
      Indicates that the built-in 100 Ohm termination resistor on the LVDS
      output is enabled. This property is optional and controlled via the
      HS_EN bit in the LVDS_CTRL register. Enabling it can improve signal
      quality and prevent visual artifacts on some boards, but increases
      power consumption.

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