The current supported Ocelot chips are the VSC7514 (link below) and the
VSC7513. Chapter 6 of this PDF links a second PDF, and you should be
able to find the Serial GPIO definitions in DEVCPU_GCB:SIO_CTRL on page
79 of that PDF.

I'm working on support for the VSC7511/7512, so I can run a "does it
work" test, but I likely won't have a setup to test the corner
conditions this patch set is addressing with any confidence.
