The only real restriction at vim2m is that width should be multiple of two, as the copy routine always copy two pixels each time. However, Bayer formats are defined as having a 2x2 matrix. So, odd vertical numbers would cause color distortions at the last line. So, it makes sense to use step 2 for vertical alignment on Bayer. With this patch, the reported formats for video capture will be: [0]: 'RGBP' (16-bit RGB 5-6-5) Size: Stepwise 32x32 - 640x480 with step 2/1 [1]: 'RGBR' (16-bit RGB 5-6-5 BE) Size: Stepwise 32x32 - 640x480 with step 2/1 [2]: 'RGB3' (24-bit RGB 8-8-8) Size: Stepwise 32x32 - 640x480 with step 2/1 [3]: 'BGR3' (24-bit BGR 8-8-8) Size: Stepwise 32x32 - 640x480 with step 2/1 [4]: 'YUYV' (YUYV 4:2:2) Size: Stepwise 32x32 - 640x480 with step 2/1 [5]: 'BA81' (8-bit Bayer BGBG/GRGR) Size: Stepwise 32x32 - 640x480 with step 2/2 [6]: 'GBRG' (8-bit Bayer GBGB/RGRG) Size: Stepwise 32x32 - 640x480 with step 2/2 [7]: 'GRBG' (8-bit Bayer GRGR/BGBG) Size: Stepwise 32x32 - 640x480 with step 2/2 [8]: 'RGGB' (8-bit Bayer RGRG/GBGB) Size: Stepwise 32x32 - 640x480 with step 2/2 Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
