#1402633 — [GIT PULL 0/7] ARM: SoC changes for 4.7

Hi Linus,

These are the first seven pull requests for arm-soc this time, there is
one small follow-up coming once the dependencies for that have landed
in your tree.

Things remain relatively calm for us. We merged 122 pull requests with
822 patches, plus 35 individual patches, which is less than what we used
to have. We are shifting even more towards changing only dts files,
for the most part adding new functionality on existing boards, and adding
new machines, as shown clearly by the dirstat:

My feeling is that the number of dts changes remain constant, but
everything else gets less every time, and that's good.

One part that sticks out this time in the dirstat this time is the
NVIDIA rework for the USB PHY, which had complex interdependencies so
we are merging all the subsystem specific change through arm-soc.

I currently don't see any conflicts against other trees, or between
our branches.

The most active individual developers (15 patches or more) out of the 165 people
that contributed this time were:

     51 Geert Uytterhoeven
     42 Simon Horman
     23 Heiko Stuebner

#1402634 — [GIT PULL 1/7] ARM: SoC cleanups and fixes for v4.7

The following changes since commit bf16200689118d19de1b8d2a3c314fc21f5dc7bb:

----------------------------------------------------------------
ARM: SoC cleanups and fixes for v4.7

Traditionally we've had two separate branches for cleanups and non-critical
bug fixes, but both of these got smaller with each release and the differences
are rather unclear now, so it seems more appropriate to have a combined
branch.

The most notably change is for OMAP, which gets a small rework to simplify
handling of the AUXDATA mechanism used on machines that are not completely
DT based yet, along with other work that is used as preparation for dropping
the legacy board files.

I happen have a script... (I run it every time people complain about DT).

Once this goes to 0, we can move the dts files out of the kernel and
make you maintainer. ;)

The dts files' numbers do look pretty constant.

Ah nice. I've done the statistics before (last time for ELC 2015 when
I did a presentation on this), but the last few lines look particularly
nice.

It's also worth comparing this to the earlier times, as by 2.6.39 we
had already started some large-scale cleanups:

This is v2.6.32..v2.6.39:
