Hi Joerg,

Hello,

The OMAP3 ISP driver was the only user of the OMAP IOVMM API. Now
that is has been ported to the DMA API, remove the unused virtual
memory manager.

The removal is split in three patches to ease upstream merge. The
first patch removes the omap-iovmm driver, the second patch
removes setting of now unused platform data fields from arch code,
and the last patch cleans up the platform data structure.
Thanks for the revised series, it looks good. I have also tested the
series on OMAP3, OMAP4 and OMAP5.

For the changes in the entire series,
Acked-by: Suman Anna <redacted>
Thank you.

I'd like to get at least the first patch merged in v3.17. To avoid
splitting the series across three kernel versions, it would be
nice to also merge at least the second patch for v3.17. If there's
no risk of conflict everything could be merged in one go through
the ARM SoC tree. Otherwise a stable branch with patch 1/3 will be
needed to base the arch change on.

Joerg, Tony, how would you like to proceed ?
The v3.17 merge window is getting close, it's probably too late to
merge patch 2/3. Joerg, could you please take 1/3 in your tree for
v3.17 ? 2/3 and 3/3 would then get in v3.18. Tony, how would you like
to proceed for those ?
How about Joerg maybe do an immutable branch against v3.16-rc1
with just these three patches and merge it into your tree?

That way I too can merge the minimal branch in if there are conflics.
If that works for Joerg, then for arch/arm/*omap* changes:

I've created an immutable branch (or, rather, immutable until the changes
reach mainline, at which point I will remove the branch) on top of
v3.16-rc1 with just the three patches from this series. You can find it
at.

Tony, is there still time to get this (and especially patch 2/3, which
touches arch/ code) in v3.17 ?
Yes as long as Joerg is OK to merge that branch in :)
Are you ? :-)
