This series fixes a long standing interaction issue between the kernels early debug facilities and the i.MX clock drivers.

This is fixing some issue but not regression. As the change basically has influence on all i.MX platforms, my take is that we should get them into linux-next for extensive testing and queue for 4.4. Agree?
Absolutely, this fixes a bug which should mostly hit developers running with earlyprintk or earlycon, so it's definitely not fixes material.
Please queue it up for 4.4.
Patches look mostly ok to me, but this certainly feels like some generic problem that we should handle in the core. Perhaps it would make sense to move this over to using the handoff mechanism Mike is working on, where we keep the clock on until a consumer grabs a reference to the clock?
So I'm not opposed to merging this for 4.4, but I'd like to see it become a generic solution sometime soon, instead of staying as a one-off fix for imx platforms.
