The new format will be called V4L2_PIX_FMT_Y10P.
It is similar to the V4L2_PIX_FMT_SBGGR10P family formats
but V4L2_PIX_FMT_Y10P is a grayscale format.

+Grey-scale image as a MIPI RAW10 packed array
+
+
+Description
+===========
+
+This is a packed grey-scale image format with a depth of 10 bits per
+pixel. Every four consecutive pixels are packed into 5 bytes. Each of
+the first 4 bytes contain the 8 high order bits of the pixels, and
+the 5th byte contains the 2 least significants bits of each pixel,
+in the same order.
+
+**Bit-packed representation.**
