Trying to connect two TPG's to Video Mixer streaming. Can this be done? TPG's have output ports required but the Mixer driver doesnt seem to support this on the layers. Correct?

The drivers for the TPG and the video mixer are using different frameworks: TPG driver is a v4l2 driver and the video mixer is a KRM DMS driver. So you will not be able to connect them and use the driver.
You could always configure the 2 IP directly through their register space in the linux user space, not using their driver.
Else you need to push the data from the TPG to memory and then read back from memory to the video mixer.

This should be handled by the linux driver.
You might want to refer to the VCU TRD. It has an example of multistream using the Video Mixer

The TRD has the mixer output to HDMI. If the ouput is to DisplayPort via a framewriter, what's should the the mixer output be connected to in the device tree? kmssink complains if there is no connector.
