There is indeed a single dts in mainline, but depthcharge will use the revision
to match the compatible string (e.g. it will look for google,nyan-big-rev5, not
google,nyan-big), so we need to list them all in that single dts. Otherwise,
depthcharge will fall back to the default config, which may or may not be
suitable for nyan.
