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.
