For GPIO bank1, context is never lost so wake-ups work without the wakeirqs handled by pinctrl-single.c. But you should not hit this unless you've configured the system to hit off mode during idle by setting /sys/kernel/debug/pm_debug/enable_off_mode and configuring UART autosuspend. So it seems the runtime_suspend/resume edge configuration for wake-up events causes it? If nothing else helps, I guess one option would be to implement pm_runtime_use_autosuspend() with the timeout configured to 100ms or something similar. But that seems like a workaround and won't fix the real issue.
