STMicroelectronics STM32 CEC driver
Required properties:
- compatible : value should be "st,stm32-cec"
- reg : Physical base address of the IP registers and length of memory
mapped region.
- clocks : from common clock binding: handle to CEC clocks
- clock-names : from common clock binding: must be "cec" and "hdmi-cec".
- interrupts : CEC interrupt number to the CPU.
Example for stm32f746:
cec: cec@40006c00 {
compatible = "st,stm32-cec";
reg = <0x40006C00 0x400>;
interrupts = <94>;
clocks = <&rcc 0 STM32F7_APB1_CLOCK(CEC)>, <&rcc 1 CLK_HDMI_CEC>;
clock-names = "cec", "hdmi-cec";
};
