1* Amlogic Meson AO-CEC driver
2
3The Amlogic Meson AO-CEC module is present is Amlogic SoCs and its purpose is
4to handle communication between HDMI connected devices over the CEC bus.
5
6Required properties:
7  - compatible : value should be following depending on the SoC :
8	For GXBB, GXL, GXM, G12A and SM1 (AO_CEC_A module) :
9	"amlogic,meson-gx-ao-cec"
10	For G12A (AO_CEC_B module) :
11	"amlogic,meson-g12a-ao-cec"
12	For SM1 (AO_CEC_B module) :
13	"amlogic,meson-sm1-ao-cec"
14
15  - reg : Physical base address of the IP registers and length of memory
16	  mapped region.
17
18  - interrupts : AO-CEC interrupt number to the CPU.
19  - clocks : from common clock binding: handle to AO-CEC clock.
20  - clock-names : from common clock binding, must contain :
21		For GXBB, GXL, GXM, G12A and SM1 (AO_CEC_A module) :
22		- "core"
23		For G12A, SM1 (AO_CEC_B module) :
24		- "oscin"
25		corresponding to entry in the clocks property.
26  - hdmi-phandle: phandle to the HDMI controller

30cec_AO: cec@100 {
31	compatible = "amlogic,meson-gx-ao-cec";
32	reg = <0x0 0x00100 0x0 0x14>;
33	interrupts = <GIC_SPI 199 IRQ_TYPE_EDGE_RISING>;
34	clocks = <&clkc_AO CLKID_AO_CEC_32K>;
35	clock-names = "core";
36	hdmi-phandle = <&hdmi_tx>;
