-* 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@...15000 {
-	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";
-};
