Bindings are for h/w, not drivers...
+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 ithe entry in the clocks property.
s/ithe/the/
- hdmi-phandle : phandle to the HDMI controller, see also cec.txt.
+Example:
+tegra_cec {
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";
