Unfortunately Pavel never applied the dt-bindings patch for this - only
the driver patch was applied. André already sent a kind reminder [1] and
two resends [2, 3] without success. Since it's a documentation-only
patch, maybe you could take it through the dt-bindings tree?

Even the original version [1] still applies cleanly to linux-next. :)

Thanks,
Stephan
