Hello,

This patch series adds a color space conversion test to the vsp-tests
suite. The aim is to test the "[PATCH 0/6] media: renesas: vsp1: Add
colorspace support" series that I have just posted to the linux-media
mailing list ([1]).

After a small white space cleanup (01/16), the series starts with
converting the vsp-tests suit from make to meson, to facilitate
cross-compilation. Patch 03/16 is another small cleanup that renames a
file to give it the correct extension.

The next 6 patches improve the gen-image application to properly handle
the color space conversion, implementing a pixel-perfect emulation of
the corresponding VSP hardware block. The series then moves on to
improving and expanding vsp-lib. Patch 10/16 helped me debug issues by
saving RPF input frames upon error for inspection. Patches 11/16 to
14/16 expand the library to support RGB <-> YUV conversion in pipelines.

The last two patches add a color space conversion test. Patch 15/16
introduces the new RGB <-> YUV test, without the ability to specify
color space parameters, and patch 16/16 then adds the color space
parameters.

The test requires updates to media-ctl and yavta to support setting
colorspace on video capture devices and on subdev source pads. The
corresponding patches have been posted to [2] and [3] respectively, I
expect them to be merged soon.
