I can no longer boot my MIPS Creator CI20 with this series (merged opendingux/for-upstream-timer-v8). Using screen+ttyUSB, I can see messages stopping at: ... [ OK ] Started Cgroup management daemon.

Could you suggest > things to try out to get into a bootable state ? I'm debugging it right now on jz4740, it seems to happen when the clocksource from the ingenic-timer driver is used. Is it your case? It should not happen if you have CONFIG_INGENIC_OST set. >> The big change is that the timer driver has been simplified.
