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
Example for STIH407:
sti-cec@094a087c {
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>;
};
