We had to do this spi0/spi6 flip-flop on trogdor-r0 because the spi buses got swizzled between r0 and r1. The swizzle stopped after r1, but we kept this around to support either hardware possibility and to keep trogdor-r0 working. trogdor-r0 isn't supported upstream, so this swizzle is not doing anything besides making a pattern that others tryt to copy for the EC and H1 nodes. Let's remove it and simplify the dts files. Cc: "Joseph S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
