The following changes since commit 026d9835b62bba34b7e657a0bfb76717822f9319:

  firmware: arm_scmi: Fix type error assignment in voltage protocol (2021-11-17 11:24:50 +0000)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git tags/scmi-updates-5.17

for you to fetch changes up to 94d0cd1da14af0042c8ee7c2cf401dfc321c575c:

  firmware: arm_scmi: Add new parameter to mark_txdone (2021-12-21 10:59:38 +0000)

----------------------------------------------------------------
Arm SCMI firmware interface updates for v5.17

Couple of main additions:
- Support for OPTEE based SCMI transport to enable using SCMI service
  provided by OPTEE on some platforms
- Support for atomic SCMI transports which enables few SCMI transactions
  to be completed in atomic context. This involves other refactoring work
  associated with it. It also marks SMC and OPTEE as atomic transport as
  the commands are completed once the return

Other changes involves some trace and log enhancements and a miscellaneous
bug fix.

I am aware I sent this pull request just around the same time Arnd finalised
the initial set. I have seen emails suggesting that Olof might be planning
to merge additional PR, so it would be great if this gets included in
that cut. All the changes are in -next since 21st December, so there should
be no surprises.

Thanks again and sorry for nagging.

Yeah, no worries -- I'd been letting pull requests sitting for a while over the
holidays. I've merged this into our late branch now.

Hi Sudeep,

I'm going through all the stuff that we ended up not getting into v5.17.
As you probably already know, this pull request was part of the arm/late
branch that missed out, sorry for the mistake on our end.

As the contents are still fine, I could offer to either merge the branch again
for v5.18, or I can drop it and wait for a new pull request from you, please
let me know your preference.

If any of the patches are bug fixes that you think should be in v5.17,
it would be good to have a separate pull request or patch email for the
5.17 fixes branch.

       Arnd

No worries, it was indeed a late PR.

Is it OK if I merge this tag with v5.17-rc1 as base and load it with any
new v5.18 material on the top ? I just want to avoid rebasing as the same time
some of the new material depend on these changes. Let me know if that
is fine. I am open to any other suggestions too.

Sure, I will check again, but AFAIK there were no fixes for existing bugs.

Yes, I think that is ok, as long as you start a branch from v5.17-rc1 and merge
the old contents into the new branch, rather than back-merging the -rc1 tag
into your existing branch. This way, the git history still makes sense
across the
merges.
