This driver adds support for the Tegra CEC IP. It is based on the NVIDIA drivers/misc/tegra-cec driver in their 3.10 kernel. This has been converted to the CEC framework and cleaned up. Tested with my Jetson TK1 board. It has also been tested with the Tegra X1 in an embedded product. Note of warning for the Tegra X2: this SoC supports two HDMI outputs, but only one CEC adapter and the CEC bus is shared between the two outputs. This is a design mistake and the CEC adapter can control only one HDMI output. Never hook up both HDMI outputs to the CEC bus in a hardware design: this is illegal as per the CEC specification. The CEC bus can be shared between multiple inputs and zero or one outputs, but not between multiple outputs.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
