* 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";
};
