Subject: [PATCH v2 0/6] rcar-vin: Add support for V4L2_FIELD_ALTERNATE
Date: Thu, 8 Aug 2019 03:18:44 +0200 [thread overview]
Message-ID: <20190808011850.21219-1-niklas.soderlund+renesas@ragnatech.se> (raw)
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 1/6, 2/6 and 3/6 prepares for the work by fixing a broken return
statement, use available macros and renaming a poorly variable. Patch
4/6 fixes a problem with scaling (Gen2 only) which was found when
testing alternating between V4L2_FIELD_ALTERNATE and
V4L2_FIELD_INTERLACED. Patch 5/6 is the real change adding support for
the new field format. Last 6/6 takes advantage of that the hardware
interlacer is no longer a requirement and removes a bit of ugly code as
a result.
Niklas Söderlund (6):
rcar-vin: Fix incorrect return statement in rvin_try_format()
rcar-vin: Make use of V4L2_FIELD_IS_INTERLACED() macro
rcar-vin: Rename rectangle holding the video source information
rcar-vin: Do not reset the crop and compose rectangles in s_fmt
rcar-vin: Add support for V4L2_FIELD_ALTERNATE
rcar-vin: Clean up how format is set on subdevice
