+The HDMI CEC module is present is Samsung SoCs and its purpose is to
+handle communication between HDMI connected devices over the CEC bus.

+ "samsung,s5p-cec"
+
+ - reg : Physical base address of the IP registers and length of memory
+ mapped region.
+
+ - interrupts : HDMI CEC interrupt number to the CPU.
+ - clocks : from common clock binding: handle to HDMI CEC clock.
+ - clock-names : from common clock binding: must contain "hdmicec",
+ corresponding to entry in the clocks property.
+ - samsung,syscon-phandle - phandle to the PMU system controller
+
+Example:
+
+hdmicec: cec@100B0000 {
+ compatible = "samsung,s5p-cec";
+ reg = <0x100B0000 0x200>;
+ interrupts = <0 114 0>;
+ clocks = <&clock CLK_HDMI_CEC>;
+ clock-names = "hdmicec";
+ samsung,syscon-phandle = <&pmu_system_controller>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&hdmi_cec>;
+ status = "okay";
+};
