Looks like there is still a conflict.  Sure, it's not a complicated
fix, but that's beside the point.  What tree is this set based on?

In what upstream tree is this line present?

It must be applied on top of my rc5t619 rtc series here:
https://lore.kernel.org/lkml/20191220122416.31881-1-andreas@kemnade.info/

I expected it to make it into 5.6 and when I first sent the RTC series
 (in October) I had no idea when I will continue with other stuff.

That is why I sent this ADC series separately, also to give the IIO
maintainer plenty of time to review. 

Do you want me to resend all that pending stuff together in one series?
I have little experience with this multi-subdevice process.

Regards,
Andreas

If a patch-set can or should be applied on its own, you should send it
based on an upstream commit, or else things like this happen.

My advice would be to maintain topic branches, each based on an
upstream release, which you can merge together into an integration
branch for full coverage testing.

It makes more sense to rebase this set onto the latest full release
and resubmit this set on its own.

It cannot without breaking bisectability. The RTC series adds IRQ support in
the PMIC which is used here.

So, I resend the RC5T619 RTC series mentioned above as you answered
upont Nikolaus question and wait with this series until review is
through.
Ok, so wait and rebase it onto 5.7-rc1 or 5.8-rc1 or whatever release
the RTC stuff will appear.
So you are not going to create an ib-mfd-rtc-iio branch.

Then Kconfig should reflect that.

Or, if that's not possible, then you should not break-up and submit
sets which cannot be applied by themselves.  Either submit the whole
set together, or submit them piece by piece, not submitting the next
part until it's predecessor has been applied.

As above.

If you go the whole-patch-set route, yes, either myself or someone
else would have to create an immutable pull-request, but you don't
have to concern yourself with that.

I will send you a complete series containing both RTC and ADC support.
Then you can decide wether you
1. apply the whole series (both things)
2. apply RTC for 5.7 and this series later
3. ignore them  (not my preferred choice ;-) ).

BTW: The way I did was based on the following note in 
Documentation/process/submitting-patches.rst

"If one patch depends on another patch in order for a change to be
complete, that is OK.  Simply note **"this patch depends on patch X"**
in your patch description."
