Kernel-4.18.0-80.el8_diu

  • Freescale Display Interface Unit

The Freescale DIU is a LCD controller, with proper hardware, it can also
drive DVI monitors.

Required properties:

  • compatible : should be “fsl,diu” or “fsl,mpc5121-diu”.
  • reg : should contain at least address and length of the DIU register
    set.
  • interrupts : one DIU interrupt should be described here.
  • interrupt-parent : the phandle for the interrupt controller that
    services interrupts for this device.

Optional properties:

  • edid : verbatim EDID data block describing attached display.
    Data from the detailed timing descriptor will be used to
    program the display controller.

Example (MPC8610HPCD):
display@2c000 {
compatible = “fsl,diu”;
reg = <0x2c000 100>;
interrupts = <72 2>;
interrupt-parent = <&mpic>;
};

Example for MPC5121:
display@2100 {
compatible = “fsl,mpc5121-diu”;
reg = <0x2100 0x100>;
interrupts = <64 0x8>;
interrupt-parent = <&ipic>;
edid = [edid-data];
};
