+* Amlogic Meson AO-CEC driver
+
+The Amlogic Meson AO-CEC module is present is Amlogic SoCs and its purpose is
+to handle communication between HDMI connected devices over the CEC bus.
+
+Required properties:
+  - compatible : value should be following
+       "amlogic,meson-gx-ao-cec"
+
+  - reg : Physical base address of the IP registers and length of memory
+         mapped region.
+
+  - interrupts : AO-CEC interrupt number to the CPU.
+  - clocks : from common clock binding: handle to AO-CEC clock.
+  - clock-names : from common clock binding: must contain "core",
+                 corresponding to entry in the clocks property.
+  - hdmi-phandle: phandle to the HDMI controller
+
+Example:
+
+cec_AO: cec@100 {
+       compatible = "amlogic,meson-gx-ao-cec";
+       reg = <0x0 0x00100 0x0 0x14>;
+       interrupts = <GIC_SPI 199 IRQ_TYPE_EDGE_RISING>;
+       clocks = <&clkc_AO CLKID_AO_CEC_32K>;
+       clock-names = "core";
+       hdmi-phandle = <&hdmi_tx>;
+};
