+Subject: [PATCH] media: v4l: Add 14-bit raw greyscale pixel format
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.

++Grey-scale image
++
++
++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.
