Kernel-4.18.0-80.el8_stih-cec

STMicroelectronics STIH4xx HDMI CEC driver

Required properties:

  • compatible : value should be “st,stih-cec”
  • reg : Physical base address of the IP registers and length of memory
    mapped region.
  • clocks : from common clock binding: handle to HDMI CEC clock
  • interrupts : HDMI CEC interrupt number to the CPU.
  • pinctrl-names: Contains only one value - “default”
  • pinctrl-0: Specifies the pin control groups used for CEC hardware.
  • resets: Reference to a reset controller
  • hdmi-phandle: Phandle to the HDMI controller, see also cec.txt.

Example for STIH407:

sti-cec@94a087c {
compatible = “st,stih-cec”;
reg = <0x94a087c 0x64>;
clocks = <&clk_sysin>;
clock-names = “cec-clk”;
interrupts = <GIC_SPI 140 IRQ_TYPE_NONE>;
interrupt-names = “cec-irq”;
pinctrl-names = “default”;
pinctrl-0 = <&pinctrl_cec0_default>;
resets = <&softreset STIH407_LPM_SOFTRESET>;
hdmi-phandle = <&hdmi>;
};
