When RDK X5 receives MIPI YUV422, why does UYVY become YUYV in DDR?

A developer receiving data on the RDK X5 via MIPI CSI-2 (DT=0x1E, pack_mode=1, 1080×2912, wstride 2160) found that the image area parses correctly as YUYV but shows wrong colors as UYVY, and that the 16-bit depth and metadata at the frame tail must be byte-swapped every 2 bytes before they can be parsed; GMSL Pixel Mode and Tunnel Mode give the same result.
