Hi Olof, Arnd and Kevin,
I have sent these patches a week ago but I have not properly addressed
them to you, so you might have missed them. The original submission is
here: http://lkml.org/lkml/2014/10/31/372.
Changes vs v1: Dropped the defconfig change that is now in mainline.
Please consider this series for addition to the arm-soc tree.
This patchset adds device tree support for ARM's AArch64 Juno development
board. It enables use of various peripherals on the board, from USB and
networking to I2C and PL011 UART.
The patches can also be found in the repository at:
git://github.com/ARM-software/linux.git juno/dts-for-armsoc
for you to fetch.
Best regards,
Liviu

DT files used in the compilation phase can be preprocessed by the C
preprocessor. This requires an include/dt-bindings directory to be
present in the arch/arm64/boot/dts directory.

We've applied the series that creates subdirectories per vendor, so
this won't apply. Care to respin on top of our next/cleanup branch?

These cpus are not ordered by reg, they probably should be (i.e. 57s
before 53s).

This dt is just a pile of nodes in a flat directory today. You're not
the first to add psci at toplevel, but it'd be nice to do some sort of
structure for this at some point.
Same for the timer and pmu nodes, they should probably go somewhere
else than the top.

We're trying to encourate DT contents to be sorted per unit address /
reg, to cause fewer conflicts when new stuff is added. Care to reorder
the devices based on that?

phy@0? Hmm. Doesn't seem to belong in the same address space as
everything else here.

Can you please add a space after colon, like you did for non-CPU nodes?

Hi Andreas,
TBH I wasn't sure a license was needed. Most (all?) of ARM's DT
files don't seem to carry a license, but I will add the appropriate
license. And yes, it is dual-licensed (GPLv2 or BSD)

I will add something to the tune: "ARM Juno development board (r0)" ? Not sure
that the format usually is.

That's because the A53s are the boot cluster. And yes, HW guys though it
was fun to confuse people by making the little cluster second in line.
Is that a hard requirement to order by reg or can I keep the current
order? AFAIK (but I need to check tomorrow with the board) the boot
code gets confused if the first node is not the boot node.

I agree and apologise for the linear dump. I know that there are other
platform coming but I don't have enough details on what parts are going
to end up being common and what not.
As for psci, should I create a small include file that contains just the
psci node and include that?

OK, I will try to break this DT in pieces.

And the bindings are not defined either. I wonder if I need to define
this at all after my patch to add the SMSC USB334x PHY ID. Will check
tomorrow when I have access to the board.
Thanks for reviewing this!
