* 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";
|
|
};
