Qualcomm dual DSI Display on AOSP

I have a SM8250 Qualcomm-based board with two different displays connected to the two available DSI ports. The drivers are implemented in the kernel and both displays work independently when each is declared as primary in the device tree. However when one is primary, and the other secondary. After the drivers are loaded, the callbacks to display on the secondary display is never called. I assume the AOSP does not consider the existence of the second DSI display and I do not how to declare it for the system.
