[GIT PULL] memory: Tegra memory controller for v5.14

[GIT PULL] memory: Tegra memory controller for v5.14

[Krzysztof Kozlowski]

Hi Olof and Arnd,

Tegra memory controller driver changes with necessary dependency from Thierry
(which you will also get from him):
1. Dmitry's power domain work on Tegra MC drivers,
2. Necessary clock and regulator dependencies for Dmitry's work.


Hi Thierry and Will,

This is the pull for you to base further SMMU aptches (prevent early SMMU
faults).

Best regards,
Krzysztof

  memory: tegra: Implement SID override programming (2021-06-03 21:50:43 +0200)

----------------------------------------------------------------
Memory controller drivers for v5.14 - Tegra SoC

1. Enable compile testing of Tegra memory controller drivers.
2. Unify Tegra memory controller drivers. From Thierry Reding:
   "This set of patches converges the feature sets of the pre-Tegra186
   and the post-Tegra186 memory controller drivers such that newer chips
   can take advantage of some features that were previously only
   implemented on earlier chips."
3. Implement SID override programming as part of work to prevent early
   SMMU faults.
4. Some simplifications, e.g. use devm-helpers.

This pulls dedicated tag from Thierry Reding with necessary changes to
Tegra memory controller drivers, as a pre-requisite to series applied
here.  The changes from Thierry's tree also include their own
dependencies: regulator and clock driver changes.

This is a tonne of code for me to pull into the SMMU tree given that I only
want one patch!

Thierry, if I just stick:

https://lore.kernel.org/r/20210603164632.1000458-4-thierry.reding@gmail.com

on its own branch, can you stitch together whatever you need?

I'm not sure I understand what you're proposing. For reference, here's
the set of patches that I sent out:

  1. memory: tegra: Implement SID override programming
  2. dt-bindings: arm-smmu: Add Tegra186 compatible string
  3. iommu/arm-smmu: Implement ->probe_finalize()
  4. iommu/arm-smmu: tegra: Detect number of instances at runtime
  5. iommu/arm-smmu: tegra: Implement SID override programming
  6. iommu/arm-smmu: Use Tegra implementation on Tegra186
  7. arm64: tegra: Use correct compatible string for Tegra186 SMMU
  8. arm64: tegra: Hook up memory controller to SMMU on Tegra186
  9. arm64: tegra: Enable SMMU support on Tegra194

Krzysztof already picked up patch 1 and I was assuming that you'd pick
up 2-6 because they are to the ARM SMMU driver. However, if you're
primarily interested in just patch 3, which is more "core" ARM SMMU than
the rest, which are Tegra-specific, then I suppose what we could do is
for you to give an Acked-by on the rest (2, 4-6) and then Krzysztof or I
can pick them up and take them via ARM SoC, based on the stable branch
from your tree that only has patch 3.

Patch 6 touches arm-smmu-impl.c, though it's a two-line change that
touches only the Tegra-specific matching bit in arm_smmu_impl_init(), so
the likelihood of that conflicting with anything else is fairly small.

Is that what you were proposing?

I think you previously said that patch 5 depends on patch 1, so I can't
take 2-6 without also pulling in the memory controller queue.

I can queue as much or as little of 2-6 as you like, but I would like to
avoid pulling in the memory controller queue into the arm smmu tree. But
yes, whichever of those I take, I can put them on a separate branch so
that you're not blocked for the later patches.

You have a better handle on the dependencies, so please tell me what works
for you. I just want to make sure that at least patch 3 lands in my tree,
so we don't get late conflicts with other driver changes.

Yes, if you could pick up patch 3 and send out a link with the stable
branch, I think Krzysztof or I could pull in that branch and pick up the
remaining patches. It'd be good if you could also ack the remaining SMMU
patches so that ARM SoC knows that they've been sanctioned.

Krzysztof: would you be okay with picking up patches 2 and 4-6 on top of
your memory branch for v5.14?

Yes, if you could pick up patch 3 and send out a link with the stable
branch, I think Krzysztof or I could pull in that branch and pick up the
remaining patches. It'd be good if you could also ack the remaining SMMU
patches so that ARM SoC knows that they've been sanctioned.

Krzysztof: would you be okay with picking up patches 2 and 4-6 on top of
your memory branch for v5.14?

You mean the iommu patches? Yes, I can take them and later explain to
Arnd/Olof why they come through me.

Okay, great.

Will, can you provide that stable branch? Or would you prefer if I
prepared it and sent you a pull request? We're kind of running out of
time, since for ARM SoC the cut-off point for new material is usually
-rc6 and that's coming up pretty fast.

Okay, great.

Will, can you provide that stable branch? Or would you prefer if I
prepared it and sent you a pull request? We're kind of running out of
time, since for ARM SoC the cut-off point for new material is usually
-rc6 and that's coming up pretty fast.

Hi Olof and Arnd,

Just FYI, the stable tag from Thierry which I pulled here (and you will
get from him as well) might cause COMPILE_TEST failures on specific
configurations. Regular defconfigs and allyes/allmod should not be affected.

I am giving heads up in case this lands in Linus later...

There will be two fixes for this, sent already by Thierry:
https://lore.kernel.org/lkml/20210609112806.3565057-1-thierry.reding@gmail.com/

1. reset controller stubs: going via reset tree,
2. reserved memory section: probably going via my tree later.


Best regards,
Krzysztof
