The goal of my patchset was to be aligned with DRM / KMS development and to offer the possibility to make a correct video playback on STiH407/STiH410 platform. Our milestone is the 4.8 for that. Currently people need these patches to work. I'm not sure it's a good time to re-evaluate the whole thing. Is it possible to re-evaluate later ? Are you OK to break ABI later?

If the answer to either question is "yes", then I'm OK to put it aside for now. But if the answer to both is "no", and this patch series is breaking ABI, then we really should fix it now. Hi Mike, i m ok to break ABI later. Hi Gabriel, This change never received any other reviews, and no pings before v4.7 was released. Sorry that it fell through the cracks, but always feel free to re-ping leading up to the merge window. Can you rebase this against -rc1? Also, do you have a plan to rework the binding to move away from the one-node-per-clock style? Regards, Mike Hi Mike, Ok i will send a v3 rebased on a rc1. Concerning the binding rework, i plan to start work at the end of October. Thanks Gabriel Many Thanks ! Best Regards Gabriel.

If yes, why not do what Maxime did for the Allwinner/sunxi clocks and just fully convert over to a one-node-per-clock-controller binding? This one-node-per-clock stuff is pretty unfortunate, and if we're deprecating platforms (patch #1) then now might be a good time to re-evaluate the whole thing.
