both the meson6_timer driver and the .dts currently only specify one
interrupt and nothing else

I have .dts patches in my tree which add the missing interrupts and the clocks
however, I prefer to send the .dts patches later as I have two other
pending patch series which are modifying the same .dts files
thus I'd like to re-send the two patches from this series (with your
Reviewed-by) together with the .dts changes

can you please confirm that Kevin can take everything through his
linux-amlogic tree (dt-bindings patches probably in his drivers
branch, .dts patches in his dt branch) if the clocksource maintainers
don't care either?


Regards
Martin
