Kernel-4.18.0-80.el8_meson-ao-cec

  • Amlogic Meson AO-CEC driver

The Amlogic Meson AO-CEC module is present is Amlogic SoCs and its purpose is
to handle communication between HDMI connected devices over the CEC bus.

Required properties:

  • compatible : value should be following
    “amlogic,meson-gx-ao-cec”

  • reg : Physical base address of the IP registers and length of memory
    mapped region.

  • interrupts : AO-CEC interrupt number to the CPU.

  • clocks : from common clock binding: handle to AO-CEC clock.

  • clock-names : from common clock binding: must contain “core”,

      corresponding to entry in the clocks property.
    
  • hdmi-phandle: phandle to the HDMI controller

Example:

cec_AO: cec@100 {
compatible = “amlogic,meson-gx-ao-cec”;
reg = <0x0 0x00100 0x0 0x14>;
interrupts = <GIC_SPI 199 IRQ_TYPE_EDGE_RISING>;
clocks = <&clkc_AO CLKID_AO_CEC_32K>;
clock-names = “core”;
hdmi-phandle = <&hdmi_tx>;
};
