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
