in another thread,
For iMX6DQ, there are two IPUs, so they can support up to 4 cameras at the same time. But the default BSP can only support up to two cameras at the same time.
The attached patch can make the BSP support up to 4 cameras based on 3.10.53 GA 1.1.0 BSP.
The 4 cameras can be:
- 1xCSI, 3xMIPI
- 2xCSI, 2xMIPI
For 4xMIPI case, the four cameras should be combined on the single MIPI CSI2 interface, and each camera data should be transfered on a mipi virtual channel.
Question, can you help to give explain to "1xCSI, 3xMIPI"? How about "3xCSI, 1xMIPI"?Why 4xMIPI four cameras shoule be combined on the single MIPI CSI2 interface?
