Hi all,

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

  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.

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
