I think the i.MX8Q P9.0.0_2.1.0-AUTO-ga release camera MAX9286 driver has some problem,when I use MAX9286 and four cameras on mek board,I can only use dev/video0 camera,other cameras dev/video1 video2 and video3 can not used.
Does the driver only support one camera?How can support all four cameras？
Please give help.

What is 8QXP b0?In the released document both 8QM and 8QXP write:
• Stream Multiplexing
• Differentiates multiple cameras from a single 4 lane MIPI input
And from System Block Diagram diff is MIPI CSI2 1x or 2x,others no diff.
Could u explain detail about 8QXP HW limited?
8QXP b0 means soc version: b0, currently 8qxp b0 mipi csi2 do not support virtual channel.
Except for virtual channel 0, virtual channels 1, 2, and 3 do not have proper VSYNC timing from MIPI CSI2 when different cameras are multiplexed together. As a result, frames stored in memory can be corrupted due to missing last lines.
This will be fixed lately.
