The Allwinner Timings Controller has two, mutually exclusive, channels. When the binding has been introduced, it was assumed that there would be only a single user per channel in the system. While this is likely for the channel 0 which only connects to LCD displays, it turns out that the channel 1 can be connected to multiple controllers in the SoC (HDMI and TV encoders for example). And while the simultaneous use of HDMI and TV outputs cannot be achieved, switching from one to the other at runtime definitely sounds plausible. Add an extra property, allwinner,tcon-channel, to specify for a given endpoint which TCON channel it is connected to, while falling back to the previous mechanism if that property is missing.

README
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.
