I.MX8MP capture MIPI embedded data

Hi NXP Community,

I would like to connect a MIPI camera to a NXP I.MX8MP based board.

The camera is streaming besides the actual frame data with MIPI data type 0x2A a 128 byte embedded header with 0x12 MIPI data type. It would be possible to capture the header with I.MX8MP?

According to i.MX 8M Plus Applications Processor Reference Manual, Rev. 1, 06/2021 section 13.5.6.13 0x12 data type is not in the list but I'm not sure if it is not supported or it is supported but it was not added to the list.

Also I would like to have, if 0x12 data type is supported, one of the ISI units configured for 0x2A DT image data on /dev/video0 capture device and second ISI channel set for 0x12 data and capture on /dev/video1

Do you thinnk the previous configuration is possible?

Thank you

imx8mp should have the same CSI IP as imx8mm, I checked the reference manual of imx8mm, should support 0x12 on HW, but as I known, current bsp (SW) doesn't support meta data
