linux-next: manual merge of the tegra tree with the arm-soc tree

linux-next: manual merge of the tegra tree with the arm-soc tree

[Stephen Rothwell]

[-- Attachment #1.1: Type: text/plain, Size: 1166 bytes --]

Hi all,

Today's linux-next merge of the tegra tree got a conflict in:

  arch/arm64/configs/defconfig

between commit:

  39bab7bfb7d9 ("arm64: configs: Remove useless UEVENT_HELPER_PATH")

from the arm-soc tree and commit:

  01d6fb565b4a ("arm64: defconfig: Add Tegra194 PCIe driver")

from the tegra tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

linux-next: manual merge of the tegra tree with the arm-soc tree

[-- Attachment #1.1: Type: text/plain, Size: 1418 bytes --]

Hi all,

Today's linux-next merge of the tegra tree got a conflict in:

  arch/arm/configs/tegra_defconfig

between commit:

  67c70aa86f8b ("arm/arm64: defconfig: Update configs to use the new CROS_EC options")

from the arm-soc tree and commit:

  3a3cb021b038 ("ARM: tegra_defconfig: Enable options useful for Nexus 7 and Acer A500")

from the tegra tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating

It was almost at the top of the branch, so I ended up just taking it out now, it
should be gone from the soc tree by tomorrow.

I think I managed to skip it as you asked on my first pass, but then failed to
reread the message when I went through the remaining entries in patchwork.

Clearly my tooling still needs  a bit of improvement.

Olof, Arnd,

There was a bit of back and forth on this because there happened to be a
conflict with the USB tree. I tried to clarify this as replies to the PR
request:

	http://patchwork.ozlabs.org/patch/1254523/

But I suspect you may have missed those replies. The bottom line is,
there is a v2 of the pull request that has the patches that are now in
the Tegra tree. That's already part of a PR that went in through the USB
tree as a dependency to resolve the conflict.

So as a result there should be no need for ARM SoC to carry that PR. But
if you still want to merge it, please pull v2, which is here:

	git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux.git tags/tegra-for-5.7-phy-v2

Sorry for the confusion,
Thierry

linux-next: manual merge of the tegra tree with the arm-soc tree

[Stephen Rothwell]

[-- Attachment #1.1: Type: text/plain, Size: 1328 bytes --]

Hi all,

Today's linux-next merge of the tegra tree got conflicts in:

  drivers/phy/tegra/Kconfig
  drivers/phy/tegra/xusb.c

between commits:

  5a00c7c7604f ("phy: tegra: xusb: Add usb-role-switch support")
  23babe30fb45 ("phy: tegra: xusb: Add usb-phy support")
  d74ce0954cb2 ("phy: tegra: xusb: Add support to get companion USB 3 port")
  58e7bd08b569 ("phy: tegra: xusb: Add Tegra194 support")

from the arm-soc tree and commit:

  f67213cee2b3 ("phy: tegra: xusb: Add usb-role-switch support")
  e8f7d2f409a1 ("phy: tegra: xusb: Add usb-phy support")
  5a40fc4b934c ("phy: tegra: xusb: Add support to get companion USB 3 port")
  1ef535c6ba8e ("phy: tegra: xusb: Add Tegra194 support")

from the tegra tree.

These are slightly different patches (the latter has been rebased).
Also there are further commits affecting these files in the tegra tree.

I fixed it up (I just used the version from the tegra tree) and can
carry the fix as necessary. This is now fixed as far as linux-next is
concerned, but any non trivial conflicts should be mentioned to your
upstream maintainer when your tree is submitted for merging.  You may
also want to consider cooperating with the maintainer of the conflicting
tree to minimise any particularly complex conflicts.

linux-next: manual merge of the tegra tree with the arm-soc tree

Hi all,

Today's linux-next merge of the tegra tree got a conflict in arch/arm64/configs/defconfig between commit e324654294907a4 ("ARM: use "depends on" for SoC configs instead of "if" after prompt") from the arm-soc tree and commit 099a6644f5be4 ("soc/tegra: Provide per-SoC Kconfig symbols") from the tegra tree.

I fixed it up (see below) and can carry the fix as necessary (no action

No need to rebase. We can resolve this by merging the clksrc/cleanup
into your branch when we pull it, or you can merge it yourself.

Thanks. This resolution looks fine.

Arnd/Olof, do you want me to rebase the Tegra branch onto some arm-soc
branch to resolve this conflict, or are you happy to simply resolve it
as below when pulling the Tegra branches into arm-soc for 3.10?

I'll send a patch to Linus at the end of the merge window, no need to
do it through a merge -- that way it's trivial for him to fixup a
merge conflict (and he can refuse to take it if he feels it's silly).

Ah, yes, they should be sorted. But definitely not right now since
it'll just make things worse.

That only works well if the one maintainer is the only person taking
patches for the drivers/clocksource tree. It might be true that the "one
maintainer" here ends up being arm-soc in this kernel cycle though?

I think this is talking about Makefile entries rather than struct
definitions?

Actually, Russell wen through and reordered these not long ago, if I
remember correctly. The current ordering is the same as in the
structure definition, and should be kept that way.

Given that the maintainer can quite safely do the patch (sorry
maintainers), I don't see any reason why it couldn't be done at the
point where they stop accepting patches for the merge-window. Once the
patches are stopped, sort the list in one last patch.

It makes sense to get it done in this window if possible as the Kconfig
will only get bigger as time goes on, making sorting it more time
consuming.

Sounds like a good idea, but the issue is: When to do the initial sort
so it doesn't conflict with all the adds in a kernel cycle... Post and
immediately commit a new patch near the end of the merge window?

I don't know about everyone else, but I feel the preference should be to
keep things alphabetized where possible to help avoid with merge
conflicts later on. This is always a problem when we start tacking
things on the end of lists.

I realise this Kconfig is not alphabetized anyway, but it's never too
early to start on the 'right' path.

Hi all,

Today's linux-next merge of the tegra tree got a conflict in
drivers/clocksource/Makefile between commit ff7ec345f0ec ("timer: vt8500:
Move timer code to drivers/clocksource") from the arm-soc tree and commit
ac0fd9eca3ba ("ARM: tegra: move timer.c to drivers/clocksource/") from
the tegra tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

This also affected arch/arm/mach-tegra/board-dt-tegra30.c.
