1STMicroelectronics STIH4xx HDMI CEC driver
2
3Required properties:
4 - compatible : value should be "st,stih-cec"
5 - reg : Physical base address of the IP registers and length of memory
6	 mapped region.
7 - clocks : from common clock binding: handle to HDMI CEC clock
8 - interrupts : HDMI CEC interrupt number to the CPU.
9 - pinctrl-names: Contains only one value - "default"
10 - pinctrl-0: Specifies the pin control groups used for CEC hardware.
11 - resets: Reference to a reset controller
12 - hdmi-phandle: Phandle to the HDMI controller, see also cec.txt.
