Bindings are for h/w, not drivers...
+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 ithe entry in the clocks property.
