Subject: [PATCH] media: v4l: Add 14-bit raw greyscale pixel format

Commit ae9753a04cfc8e41262605875e531b6ea5e3d0ac upstream.
|
|
|
|
The new format is called V4L2_PIX_FMT_Y14. Like V4L2_PIX_FMT_Y10 and
|
|
V4L2_PIX_FMT_Y12 it is stored in two bytes per pixel but has only two
|
|
unused bits at the top.

+Description
|
|
+===========
|
|
+
|
|
+This is a grey-scale image with a depth of 14 bits per pixel. Pixels are
|
|
+stored in 16-bit words with unused high bits padded with 0. The least
|
|
+significant byte is stored at lower memory addresses (little-endian).
|
|
+
|
|
+**Byte Order.**
|
|
+Each cell is one byte.
