There are a bunch of GPIO muxing data, but most of them are actually unneeded because GPIO-to-pin mapping can be specified by "gpio-ranges" DT properties. Tables that contain a set of GPIO pins are still needed for the named mapping by "gpio-ranges-group-names". This is a much cleaner way for UniPhier SoC family where GPIO numbers are not straight mapped to pin numbers.

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.
