Hi,
Here is a set of 11 patches for the ingenic-drm driver.
Patches 1-7 are mostly generic cleanups, which will grease up the way for bigger changes to be introduced.
Patch 3 adds support for a private state structure, which is then used to store state-specific information, which was previously stored in the driver's private structure directly.
Patch 10 is the big one; it adds a double-scan feature emulated with DMA descriptors. This trick makes it possible to support a handful of boards which have strange panels with non-square pixels (320x480 4:3).
Patch 11 updates the driver to support one top-level bridge per encoder, as it seems to be the norm now.
Cheers, -Paul
