[PATCH v2 0/7] v4l: ti-vpe: Some VPE fixes and enhancements

[Archit Taneja <archit@ti.com>]

This patch set mainly consists of minor fixes for the VPE driver. These fixes
ensure the following:

- The VPE module can be inserted and removed successively.
- Make sure that smaller resolutions like qcif work correctly.
- Prevent race condition between firmware loading and an open call to the v4l2
  device.
- Prevent the possibility of output m2m queue not having sufficient 'ready'
  buffers.
- Some VPDMA data descriptor fields weren't understood correctly before. They
  are now used correctly.

The rest of the patches add some minor features like DMA buf support and
cropping/composing.

Reference branch:

git@github.com:boddob/linux.git vpe_for_315

Changes in v2:

- selection API used instead of older cropping API.
- Typo fix.
- Some changes in patch 6/7 to support composing on the capture side of VPE.
