I can take it for v5.5 The driver change is debatable and not strictly necessary, so it probably makes more sense to take this one through the VExpress tree on its own. I wouldn't suggest flipping the status to "enabled" just yet, but it seems worth putting the basic description in place as a jumping-off point for folks to hack on (e.g. it's another 'interesting' case for devfreq OPP stuff).
