Sure, we can just drop the last patch (and the status property).

The entire clock rework series does not affect this ADC series or any
other on going series. It can be merged latter, without breaking
anything. I just realized I mentioned the clock rework series as a
dependency in the cover letter of this series but it is not, my bad.
So, we can target the next merge window for all series but the clock
rework. In addition to this, I can send a series moving the clock node,
with minor modifications to the driver so we have a proper dt. And then
we can see if moving to a regmap aware clock driver can be done.
To sum up:
- chip/system controller series can be pushed
- this ADC series too, as it does not depend on the clock rework (as
soon as we have the needed acked-by)
- I need to make a new series to move the clock node
- the clock driver rework series can live in parallel
Agreed?
