The following two patches add one new media bus code and one new pixel format.
Both are for 10bit grayscale data. They will be used by the future version of
the QComm CAMSS driver when receiving the frame data from the OV7251 grayscale
camera sensor.

The code will be called MEDIA_BUS_FMT_Y10_2X8_PADHI_LE.
It is similar to MEDIA_BUS_FMT_SBGGR10_2X8_PADHI_LE
but MEDIA_BUS_FMT_Y10_2X8_PADHI_LE describes grayscale
data.

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.

Could you add which exact bits the two LSBs of each pixel go to in the last
byte, as in the 10-bit packed Bayer format documentation?
