Here is my large patch series which cleans up imx-drm, and gets it ready to move out of drivers/staging. This is a preview only.
One of these patches introduces a generic helper in drivers/base which can be used by any subsystem to assemble a sub-devices together and complete the probe of a subsystem when all devices are present - and tear it down when any of those devices go away - this is patch 26.
Example usage (with imx-drm) is illustrated in patches 27 through to 41.
Some of this duplicates Fabio's imx-drm HDMI patch; indeed some of the changes which were fed back to Fabio are here as their individual patches. I've not updated Fabio's patch in this series since he sent an updated version to Greg for merging.
I've also included here support for ALSA based HDMI audio - if you omit the new HDMI drivers from this, it gives a net reduction in LoC.
Finally, the last patch attempts to resolve a problem with the way imx-drm works - but this is fundamentally unsolvable without introducing new DT properties to properly specify the mux IDs.
I'm only sending this to a limited number of people for comments at present since it's a large series, and the selection of people from maintainers is rather large.
