Actually, I've updated a timer implementation of mine to invoke a reset
controller similar to how you do in the STM32 clocksource patch, but no
reset controller is getting returned.

It seems to me, you are working around that by simply ignoring the error
in the timer code and not doing a reset then, so the STM32 timer does in
fact _not_ depend on the reset controller? What happened to your efforts
of making the reset controller usable for the timer? In my case, my
timer is originally in reset state and needs to be deasserted, so I
can't just ignore it.

Regards,
Andreas
