Hi all,
I am trying to integrate mipi camera(IMX219) to our IMX8MP custom board. I have to connect four IMX219 modules to iMX8MP. But it is having only 2 CSI interfaces, I'm doing it using an i2c MUX and two MIPI switches.
I'm able to get the stream from the CSI0 interface(both channel 1 and channel 2). But not with CSI1 interface (Channel 3 and channel 4). Getting the following error upon accessing the channel 3.
ERROR : [MediaPipeline] NativeSensor open error!
ERROR : [V4l2Event] initialize MediaPipeline error!
Following is the custom dts file that are using.

Attaching the dtsi file for reference.
Does it require any change to enable the second MIPI CSI interface?
Any help is appreciated.
Thanks in advance!
