-* 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 at 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";
-};
