If there are no other problems with v5, could we maybe take it as a basis and then I would submit a patch to reduce the number of IRQs?Please understand my concerns with this driver. It's a quite complex beast and experience shows that once a driver is in the kernel it is far more complicated to change it than to do it right the first way. You know that I'm also interested in having a MX31 framebuffer (and camera) driver in kernel but I want to make sure that it works properly and leaves room for feature enhancements without having to refactor the whole driver. It would be good if someone else could throw his 2 cents into this discussion.
I have been on holiday since last week and I don't really have time to comment on all this until my return from great ski weeks, but I have been following the discussion very attentively and I will for sure test and comment on these patches (camera is very important for our application) as soon as I get back to work in January. It's a bit tricky with this merge window in the "middle" of holidays for me.
