Hi Greg, I just noticed this now. I am having similar issue with MPS2 UART driver posted @[1], hence I am asking here to get some clarification myself. Sorry for replying on very old thread.

However MVEBU UART obtained 114 with v4.6-rc1 And MPS2 UART was assigned 115 when it got revised/reposted. I also see this patch in linux-next with 114 itself as its port number. So the allocation of port number needs to be resolved before it gets merged or it's OK to wait for v4.7-rc1 ? If it's former, can PORT_PIC32 take 116 as the latest post of MPS2 assigned it 115 and I have pulled the same to take it via arm-soc. I am fine with any solution, just want to be notified if I need to take any action.
