Hello,
Here's the third version of the Renesas R-Car FDP1 driver.
The FDP1 (Fine Display Processor) is a hardware memory-to-memory de-interlacer
device, with capability to convert from various YCbCr/YUV formats to both
YCbCr/YUV and RGB formats at the same time as converting interlaced content to
progressive.
Patch 01/10 fixes an issue in the V4L2 ioctl handling core code. It has been
posted before and hasn't been changed.
Patch 02/10 adds a new standard V4L2 menu control for the deinterlacing mode.
The menu items are driver specific.
Patch 03/10 extends the FCP driver to support the FDP1. It has been posted
before and hasn't been changed.
Patch 04/10 adds the FDP1 driver unchanged compared to the v2 posted by
Kieran. Patches 05/10 to 09/10 then fix issues in the driver and incorporate
review comments. They will eventually be squashed into patch 04/10, but are
currently separate to allow easier review of the changes.
Patch 10/10 reworks buffer handling in the FDP1 driver. This is experimental
and doesn't fix any known bug. I've included the patch in the series to get
feedback on whether this is a good idea.
Kieran, I noticed that your patches are authored by
Kieran Bingham <kieran@xxxxxxxxxxxxxxx>
Is that correct or should it be changed to
Kieran Bingham <kieran+renesas@xxxxxxxxxxx>
?
