[PATCHv2 00/45] Convert omapdrm to the atomic updates API

[Tomi Valkeinen]

Hi,

This is v2 of the atomic modesetting series for omapdrm. Laurent was not able
to finish the work before having to leave abroad, so I continued the work on
the series, fixing up the remaining issues and doing some additional cleanups.

It is a bit late in the kernel development cycle, but I'm hoping we could get
this into v4.2 for two reasons: 

* After these patches some long remaining issues in omapdrm are gone. We
  finally get tear-free page flipping.
* After these patches the driver is so, SO much cleaner, that fixing any new
  bugs found will be considerably easier.

There is some going back-and-forth in these patches, but that's expected with
such a big change. The kernel should compile after each patch, but omapdrm will
not function perfectly after each patch. The issues shouldn't be huge, though,
but things like fps dropping into half do happen in the middle of the series.

The series is based on the latest drm/next branch and depends on the pending
"drm: omapdrm: Store the rotation property in dev->mode_config" patch by
Daniel Vetter.

The omapdrm loses support for its custom fences in the process. This isn't
deemed to be an issue, as the custom fences API is used by the SGX driver
only, which requires out-of-tree patches anyway. Fences support will be
reimplemented at a later point on top of the atomic updates conversion using
the mainline fence API.

I have been testing this with Pandaboard, using single and dual outputs,
without any issues.

These patches can also be found from:
