The Alvium has a fixed pixel order currently what should be BGR during 
transmission of any RGB format as described in MIPI-CSI2 spec 1.3. We 
tested with MEDIA_BUS_FMT_RGB888_1X24 as well as 
MEDIA_BUS_FMT_RGB888_3X8 for RGB24 in several SoCs like imx8mm, imx8mp 
and Xilinx CSI2RX subsystem on ZynqMP and Versal.
Does that answer your question?
