my topic/st_fdma is immutable branch. You cna merge it, if you need a signed
tag, please do let me know

WHY.. Stuff is already merged twice! Please send updated on top of already
merged code! This is how kernel developement is done...

When the feedback is "there is an unrelated change in this patch", the only way
you can fix that is by having a new version of the patch.

>Please send updated on top of already

You have dropped the remoteproc parts which were updated in v11, so
it is no longer merged. Bjorn can now pick the v11 versions if he chooses which
incporporates his feedback.

Hi Vinod,

It looks like you reverted the wrong Kconfig fix, the one I objected to
was the change in drivers/remoteproc, not the one in drivers/dma.

The ST_FMDA depends on functions exposed by REMOTEPROC and
ST_SLIM_REMOTEPROC, the latter in turn depends on REMOTEPROC, which you
guys made user selectable - and as such should not be selected - but I
think we should move forward and get everything merged and then we can
go back and figure out how this should be addressed (or left alone?).

I have merged "topic/st_fdma" into rproc-next, so that I can fix up the
now broken drivers/remoteproc/Kconfig.

We do however both need to revert the revert or there will be link
errors if you build the dma driver with remoteproc=n. If you do this I
can merge the topic once more and we'll keep the set of changes in sync.

Regards,
Bjorn

Oops my bad, thanks for letting me know. I have reverted this now and
pushing out. Please do let me know if this was fine

Thanks for the update Vinod, I've merged in your updated branch into
mine, so now we should be good.
