Hi ARM SoC maintainers,

Slightly unusual for this release is that I've included two branches
that traditionally don't go through ARM SoC (clk and cpufreq). However
these are added here because they were part of a larger series to add
CPU frequency scaling support on Tegra210 and because the respective
maintainers agreed that it was a good idea to take these through ARM
SoC.

The dependencies between the branches are purely runtime dependencies,
so I haven't marked them as dependencies. They can be applied in any
order. This also means that if you'd rather not pull the requests for
clk and cpufreq, just let me know and I'll send them out to the
corresponding maintainers.

Thanks,
Thierry

Hi ARM SoC maintainers,

The following changes since commit bfeffd155283772bbe78c6a05dec7c0128ee500c:

  Linux 5.0-rc1 (2019-01-06 17:08:20 -0800)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux.git tags/tegra-for-5.1-arm64-defconfig

for you to fetch changes up to bc72bed682a9502f5c8f5adf15107aef6237895e:

  arm64: defconfig: Enable Tegra TCU (2019-02-06 14:38:35 +0100)

Thanks,
Thierry

----------------------------------------------------------------
arm64: tegra: Default configuration changes for v5.1-rc1

Enables the TCU driver to be built into the kernel, so that the TCU can
be used as debug serial on Jetson Xavier. This also enables the MAX8973
regulator driver that is required for CPU frequency scaling on Tegra210.

I see the Ack from Viresh, but I don't see why you'd like to have them
merged through the soc tree rather than the cpufreq tree.

Could you clarify? It's no problem to do it, I just want to make sure
there is a good reason for it.

Nevermind, I just found the 0/9 message that explains it all, pulled now

My understanding is that this currently only happens if we boot the
system using a DTB from a downstream build where these FUSE and BPMP
device tree nodes are sorted differently and therefore cause them to
be probed in the wrong order.

Booting an upstream kernel with a downstream DTB isn't known to work
very well in general. It's something that I hope we'll be able to do
in some distant future when the gap between upstream and downstream
DTBs has become sufficiently small, but I don't think we need to
bother fixing this in stable releases.

Adding Timo to clarify whether he thinks this is important enough to
backport.

I don't think that'd be worth it. As far as I can tell these have been
broken since forever. Backporting this would be fairly involved and I'm
not sure if this hurts enough to warrant the additional work, given that
it's not been reported in all this time.

Dmitry, can you clarify whether you want these to be backported?

Technically it fixes a real problem, but realistically there is no real need to backport these patches because of other suspend-resume troubles that also existed all the time and haven't been resolved yet (likely fixes won't be backportable). In general suspend-resume kinda works and fails mostly under some load (like stress testing), at least that's the case for T30.

Actually no, I looked up the other T30 fixes and they are pretty trivial. Moreover turned out that I already sent them out before [0] and forgot about them.. probably it's a bit too late for v5.1 now.

Still it's not really worth to backport the patches given that vanilla upstream kernel can boot only on dev boards in a case of Tegra30 because there is no support for the Trusted Foundations T30 firmware yet. Hopefully we will manage to get all the fixes and the firmware support ready for v5.2 and then everything will be in place.
