1	* Amlogic Meson AO-CEC driver
2	
3	The Amlogic Meson AO-CEC module is present is Amlogic SoCs and its purpose is
4	to handle communication between HDMI connected devices over the CEC bus.
5	
6	Required properties:
7	  - compatible : value should be following
8		"amlogic,meson-gx-ao-cec"
9	
10	  - reg : Physical base address of the IP registers and length of memory
11		  mapped region.
12	
13	  - interrupts : AO-CEC interrupt number to the CPU.
14	  - clocks : from common clock binding: handle to AO-CEC clock.
15	  - clock-names : from common clock binding: must contain "core",
16			  corresponding to entry in the clocks property.
17	  - hdmi-phandle: phandle to the HDMI controller
18	
19	Example:
20	
21	cec_AO: cec@100 {
22		compatible = "amlogic,meson-gx-ao-cec";
23		reg = <0x0 0x00100 0x0 0x14>;
24		interrupts = <GIC_SPI 199 IRQ_TYPE_EDGE_RISING>;
25		clocks = <&clkc_AO CLKID_AO_CEC_32K>;
26		clock-names = "core";
27		hdmi-phandle = <&hdmi_tx>;
28	};
