Subject: [PATCH 00/11] ingenic-drm cleanups and doublescan feature

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
