How is that transfered ? Do you have a 24-bit bus ? Or do you use an 8-bit bus 
with 3 transfers per pixel ? In the first case you will need something like 
V4L2_MBUS_FMT_RGB888_1X24, in the second case V4L2_MBUS_FMT_RGB888_3X8 (and 
the corresponding BGR formats).

Could you please detail how those three formats are transferred on the bus ?

Is that 10 bit compressed to 8 bit with alaw ? If so

V4L2_MBUS_FMT_SBGGR10_ALAW8_1X8
V4L2_MBUS_FMT_SGBRG10_ALAW8_1X8
V4L2_MBUS_FMT_SGRBG10_ALAW8_1X8
V4L2_MBUS_FMT_SRGGB10_ALAW8_1X8

should do.
