Hi,
This series adds support for V4L2_FIELD_ALTERNATE to rcar-vin. This
removes a limitation in the driver where a video sources delivering
video using the alternating field format was forced to use the rcar-vin
interlacer and V4L2_FIELD_INTERLACED was delivers to the user. After
this series the use of the interlacer is still default but the user have
the option to explicit ask for alternate.
It is based on latest media-tree and tested on R-Car Gen2 and Gen3
hardware.
Patch 1/4 prepares for the work by renaming a poorly variable, 2/4 fixes
a problem with scaling (Gen2 only) which was found when testing
alternating between V4L2_FIELD_ALTERNATE and V4L2_FIELD_INTERLACED.
Patch 3/4 is the real change adding support for the new field format.
And last 4/4 takes advantage of that the hardware interlacer is no
longer a requirement and removes a bit of ugly code as a result.
