From: Steve Longerbeam <steve_longerbeam@xxxxxxxxxx>
A set of patches that fixes some bugs with capturing from an
interlaced source, and incompatibilites between IDMAC interlace
interweaving and 4:2:0 data write reduction.
History:
v6:
- Changes to patch "gpu: ipu-csi: Swap fields according to input/output
field types" suggested by Philipp Zabel.
v5:
- Added a regression fix to allow empty endpoints to CSI (fix for imx6q
SabreAuto).
- Cleaned up some convoluted code in ipu_csi_init_interface(), suggested
by Philipp Zabel.
- Fixed a regression in csi_setup(), caught by Philipp.
- Removed interweave_offset and replace with boolean interweave_swap,
suggested by Philipp.
- Make clear that it is IDMAC channel that does pixel reordering and
interweave, not the CSI, in the imx.rst doc, caught by Philipp.
v4:
- rebased to latest media-tree master branch.
- Make patch author and SoB email addresses the same.
v3:
- add support for/fix interweaved scan with YUV planar output.
- fix bug in 4:2:0 U/V offset macros.
- add patch that generalizes behavior of field swap in
ipu_csi_init_interface().
- add support for interweaved scan with field order swap.
Suggested by Philipp Zabel.
- in v2, inteweave scan was determined using field types of
CSI (and PRPENCVF) at the sink and source pads. In v3, this
has been moved one hop downstream: interweave is now determined
using field type at source pad, and field type selected at
capture interface. Suggested by Philipp.
- make sure to double CSI crop target height when input field
type in alternate.
- more updates to media driver doc to reflect above.
v2:
- update media driver doc.
- enable idmac interweave only if input field is sequential/alternate,
and output field is 'interlaced*'.
- move field try logic out of *try_fmt and into separate function.
- fix bug with resetting crop/compose rectangles.
- add a patch that fixes a field order bug in VDIC indirect mode.
- remove alternate field type from V4L2_FIELD_IS_SEQUENTIAL() macro
Suggested-by: Nicolas Dufresne <nicolas@xxxxxxxxxxxx>.
- add macro V4L2_FIELD_IS_INTERLACED().
