If you want me to review something you'l need to submit it; that patch was from 2013 so predates me maintaining the subsystem so I've never seen a copy. My general instinct with this stuff is that it's likely to be more sensible to describe this with GPIO chip selects, the state of controller chip selects is such that a lot of devices use them anyway even when the controller supports native chip selects as the controller chip selects often suffer from unfortunate limitations that mean they're not actually useful.
