The transitional helpers (which we have been using so far) create a plane state and then use the plane's atomic entrypoints to perform the atomic begin/check/prepare/commit/finish sequence on that single plane only. The full atomic helpers create a top-level atomic state (which is capable of holding multiple object states for planes, crtc's, and/or connectors) and then passes the top-level atomic state through the full "atomic modeset" pipeline. Switching from the transitional to full helpers here shouldn't result in any functional change, but will enable us to exercise/test more of the internal atomic pipeline with the legacy API's used by existing applications.
