1* Tegra HDMI CEC hardware 2 3The HDMI CEC module is present in Tegra SoCs and its purpose is to 4handle communication between HDMI connected devices over the CEC bus. 5 6Required properties: 7 - compatible : value should be one of the following: 8 "nvidia,tegra114-cec" 9 "nvidia,tegra124-cec" 10 "nvidia,tegra210-cec" 11 - reg : Physical base address of the IP registers and length of memory 12 mapped region. 13 - interrupts : HDMI CEC interrupt number to the CPU. 14 - clocks : from common clock binding: handle to HDMI CEC clock. 15 - clock-names : from common clock binding: must contain "cec", 16 corresponding to the entry in the clocks property. 17 - hdmi-phandle : phandle to the HDMI controller, see also cec.txt. 18 19Example: 20 21cec@70015000 { 22 compatible = "nvidia,tegra124-cec"; 23 reg = <0x0 0x70015000 0x0 0x00001000>; 24 interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>; 25 clocks = <&tegra_car TEGRA124_CLK_CEC>; 26 clock-names = "cec"; 27};
