Ok, I'm somewhat lost now... are these the affected timers on sun7i following:
- allwinner,sun4i-a10-timer (timer@1c20c00)
- allwinner,sun7i-a20-hstimer (hstimer@1c60000)

Any ideas on what approach I could actually use?

Also, similar timer dependency would affect then sun6i-a31 and sun9i-a80
platforms too...
