This happening because we are missing these patches:
https://patchwork.kernel.org/patch/84748/
https://patchwork.kernel.org/patch/84749/
https://patchwork.kernel.org/patch/84755/
https://patchwork.kernel.org/patch/84750/
Not part of LO yet.
But we need these patches for uart4 support for 3630.
I have rebased the patches on top of wip-uart and tested with 3630SDP.
Attaching the same.
Regards,
Govindraj R
