This series adds an initial framework that allows to register a graphics complex as found on many SoCs with the DRM/KMS subsystem. Patch 1 adds the actual framework and patch 2 implements a very rudimentary skeleton driver on top of it. It's really just to show off how to use the DRM/SoC API and of no use otherwise.
The reason for implementing this is that the approach currently used by many SoC DRM drivers is to instantiate a dummy platform device for the DRM driver to bind against, which is somewhat of a kludge. The proposal in this series takes care of this implicitly and instantiates only what is really needed to make the DRM core happy.
I fully realize that this may not be that much of an improvement over using the drm_platform_init()/drm_platform_exit() functions, but I'm still interested in what people think about it.
