[GIT PULL 00/11] tegra: Changes for v5.8-rc1

[Thierry Reding]

Hi ARM SoC maintainers,

This set of pull requests contains a couple more driver changes than
usual, which is primarily because of some build-time and runtime
dependencies.

The biggest driver here is probably the VI/CSI driver for Tegra210
which has been extensively been reviewed on the mailing list and was
acked by two of the subsystem maintainers.

Other than that there's CPU frequency scaling work and CPU idle support
for older chips, both of which have also been acked by the corresponding
maintainers. There are also three patches to core OF support which Rob
also acked and which are a build-time dependency for the Tegra210 EMC
frequency scaling patches.

The rest is pretty standard stuff.

For last cycle you had asked subarch maintainers to help with fleshing
out pull request details. Is this something that you wanted to pursue
for this cycle as well?

This adds bindings for the CSI TPG clock on Tegra210, moves various
clocks from the clock and reset controller to the PMC where their
controls really are, adds bindings for the external memory controller
and video capture controller on Tegra210, as well as CPU frequency
scaling on Tegra20 and Tegra30.

I don't mind taking the memory driver patches, but it seems odd that this
pull request has so many drivers/clk changes but does not mention that
in the pull request, and does not Cc the clk maintainers or include Acks
from them.

I would assume that the reason for this is that you have based
the memory controller changes on a branch that was already
accepted by the clk maintainers in to their tree, but when you do that
please be more explicit so I know what is going on.

Waiting for clarification before I can pull this.

So historically there's often a lot of dependencies, either build-time
or runtime, between Tegra clock patches and other work. That's why we
ended up with this model where I collect Tegra clock patches in the
Tegra tree and it's not uncommon to end up with the clock branch being
a dependency of one of the other branches.

I did send this to Mike and Stephen about 1 1/2 weeks ago, but it does
not look like they've pulled it into the clk tree yet.

I typically highlight the dependencies in the pull request, but looks
like I forgot to do that this time around.

> Waiting for clarification before I can pull this.

Given the above, might be best to hold off on this for a bit until the
clock branch was pulled by Mike or Stephen.

I pulled the clk branch into clk-next now.

Hi Arnd,

looks like this pull request didn't make it into v5.8-rc1. Was there
anything left here that you're waiting for me to address?

Hi Arnd, Olof,

send out a v2 of this because I noticed that...

... this patch contains some leftover changelog notes that I forgot to

There's also one fix missing from this that I was meaning to apply for
v5.8 which will enable suspend/resume on Tegra186.

This is a slightly rebased version of the prior pull request which has
the commit log cleaned up as I mentioned earlier. I've also included a
patch to enable resume from suspend via the PMIC on Jetson TX1 and
Jetson Nano, which will help us to test suspend/resume in our test
system in a unified way.
