mailbox: Add Tegra HSP driver

This contains the device tree bindings and a driver for the Tegra HSP, a
hardware block that provides hardware synchronization primitives and is
the foundation for inter-processor communication between CPU and BPMP.

[GIT PULL 2/10] firmware: Add Tegra IVC and BPMP support

Thanks,

----------------------------------------------------------------
firmware: Add Tegra IVC and BPMP support

IVC is an inter-processor communication protocol that uses shared memory
to exchange data between processors. The BPMP driver makes use of this
to communicate with the Boot and Power Management Processor (BPMP) and
uses an additional hardware synchronization primitive from the HSP block
to signal availability of new data (doorbell).

Firmware running on the BPMP implements a number of services such as the
control of clocks and resets within the system, or the ability to ungate
or gate power partitions.

Hi,

Again the format of the pull request here is a little confusing, since it's
a cumulative shotlog and diffstat, while you already sent the bulk of this
as part of the driver branch (1/10). It'd have been better to use that branch
as the base when you generate the pull request since that's the delta we see
when we merge it in.

Also, I can't seem to find the key you use to sign these tags with, it isn't
uploaded on pgp.mit.edu. Can you remedy that please, and get it signed as
needed?

All that being said, I've merged this into next/drivers. Thanks!

In the past there had been occasions where it hadn't been clear what a
given branch was going to pull in as additional dependencies, so adding
the complete shortlog seemed like a good way to document this in a more
explicit way.

If you prefer working things out yourself I can tweak the scripts to
generate the pull requests on top of their respective dependencies.

It's really about the order we'll merge the patches and the diffstat that
git merge will generate and display (which is the one I usually verify
against).

So being clear is definitely useful, but doing the diffstat on the incremental
changes is still preferred.

Odd, I searched for it and didn't find it. But yeah, it's there.

The drivers->dt dependency here is annoying. Any chance you can respin without
it?

We've been encouraging people to consider using numerical clock/gpio/reset
numbers on initial submission to avoid these dependencies on dt-bindings
includes, and then follow up with a move to the symbolic names between -rc1 and
-rc2. Mind doing the same here?


Thanks!

Yes, I can do that. Would it be acceptable to have a dt-bindings->dt
dependency? Stephen's already done a good job of avoiding this kind of
dependency by getting the bindings, and hence dt-bindings headers,
merged ahead of Linux kernel support because he had already gotten the
bindings reviewed and finalized during his work on U-Boot.

I've been told in the past that it's not necessary to strictly split DT
bindings patches from driver patches, but I suppose if a dt-bindings->dt
is acceptable, then splitting things up more strictly would actually be
the preferable solution here because it also avoids the slight churn of
converting to symbolic values later on.

Sorry, haven't been looking at this older for a while so this reply is
high-latency.

If you want to do a separate dt-bindings branch that includes the headers and
is present in both the dt and drivers branch, that'd work. If the changes are
trivial though, and just contains a few clocks, I think we should just have
them opencoded on the original merge, and then move over once the include files
have gone in. I'd be willing to merge such conversions between -rc1 and -rc2.

That's in particular the case when there's an external driver tree/maintainer,
since it avoids the three-way handshake, etc.

[GIT PULL v2 9/10] arm64: tegra: Device tree changes for v4.10-rc1

  arm64: tegra: Add NVIDIA P2771 board support (2016-11-21 10:43:42 +0100)

The only change since the original pull request is the replacement of
symbolic names in DTS files by their numerical equivalents to remove the
dependency on the driver branchs, as requested by Olof.

I have three patches to reintroduce these symbols that I can resend after
v4.10-rc1.

Thanks,
Thierry

This was already in next/arm64 (but I didn't see a notification),
and with the arm64-dt branch now merged as well, we should have

I had also sent a couple of individual patches that seemed to not have
it made into v4.9 and v4.8 for some reason (they were part of the pull
requests, as far as I can tell). Do you think you could pull those in
as well?

Most likely yes, but I have trouble finding them right now. Can you
just resend them?

I don't think you really needed to merge this in here, since all you need it
for is to fulfill the kconfig dependency and enable the driver, right? That'd
happen when the driver and soc branch is merged at the toplevel anyway.


Anyhow, no damage done, I've merged this in. I would say that it'd be a little
more logical to send the SoC branch before the driver branch given this
dependency though.

The reason I did this is that I wanted each branch to be buildable as a
way to confirm that the dependencies are correct. In order to do that I
need the Kconfig symbol to enable the driver.

I suppose there are other ways I could've done that, though. Maybe in
the future new SoC Kconfig symbols should just be introduced way ahead
of time, so that they're already in a release or two before actual code
starts to emerge.

The reason that the SoC branch was sent after is because only the first
commit in that branch was pulled into the mailbox branch.

In retrospect, I think perhaps a better approach would've been to have a
separate branch with only the Kconfig symbol addition and pull that in
where needed.

Thanks,
Thierry

Good point, but that's more of a local setup thing for you, and not something
that necessarily needs to go upstream.

That'd work too!

That could work, but the whole branch-merge-features-then-enable it workflow is
quite acceptable as well.
