     * Tegra HDMI CEC hardware
     
     The HDMI CEC module is present in Tegra SoCs and its purpose is to
     handle communication between HDMI connected devices over the CEC bus.
     
     Required properties:
       - compatible : value should be one of the following:
             "nvidia,tegra114-cec"
             "nvidia,tegra124-cec"
            "nvidia,tegra210-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 "cec",
                      corresponding to the entry in the clocks property.
      - hdmi-phandle : phandle to the HDMI controller, see also cec.txt.
    
    Example:
    
    cec@70015000 {
            compatible = "nvidia,tegra124-cec";
            reg = <0x0 0x70015000 0x0 0x00001000>;
            interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&tegra_car TEGRA124_CLK_CEC>;
            clock-names = "cec";
    };
