-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>;
