  ARM: dts: move aliases back to .dts in Cygnus (2015-09-24 18:30:10 -0700)

----------------------------------------------------------------
This pull requests contains the following Broadcom SoCs Device Tree changes:

- Brian Norris documents the BCM7445 SoCs Power Management controllers and
  hardware and updates the reference BCM7445 Device Tree with these nodes

- Florian Fainelli documents the BCM7xxx write-pairing feature in the top-level
  BCM7xxx binding document

- Hauke Merthens enables the NAND controller for the Asus RT-AC87U and adds the
  GPIO pin controlling the USB power supply on Netgear R6250

- Jon Mason adds support for the NorthStar Plus SoC by providing a top-level
  binding document and the minimalist device tree skeleton for these SoCs

- Rafal Milecki adds support for the Netgear R7000 (BCM5301x SoC)

- Ray Jui provides a set of Cygnus DT changes that make the Device Tree clearer
  and more correct with respect to how the hardware is designed. He also enables
  the NAND controller on the bcm911360_entphn design, enables a bunch of
  peripherals on the bcm958305k evaluation board, and adds a skeleton .dtsi file
  for the touchscreen extansion board(s)

There are 3 other pull requests for Device Tree, SoC/driver and
MAINTAINERS file updates, is the threading confusing?

Thanks!

Yes, I guess I was confused by that.

I see now that I moved the entire mail thread into my 'done' folder.
Some other maintainers post all patches in the series as replies to
the git pull mail, and I must have assumed you did the same, or I
just didn't look when moving this thread.

I think it would help if you change the subject line to [GIT PULL 1/4],
which makes it a bit more obvious in the future.

Thanks for the report, I've now put them back into my todo folder and
should get to it by tomorrow at the latest.

Will do, just updated my script to do that.

I'm not overly happy with this part of the code (sorry Brian):

- it looks like it should be a cpuidle driver. Not completely sure about this,
  but I'd like to see at least an Ack from the cpuidle maintainers to confirm
  that they want it to be done in drivers/soc

- any code here that is not going into a cpuidle driver for this part looks
  like it's better suited to go to arch/arm/mach-bcm, as the code doesn't
  feel like a driver. This is of course a gray area, and can be debated.

- it's clearly not endian-safe. There really is no reason to use __raw
  mmio accessors here, or to define the interface to the firmware in terms
  of native endianess when the registers and firmware is known to be
  little-endian.

Sorry for not noticing the driver earlier when it was discussed on the list,
but I think the above is reason enough to do another revision.
Can you submit a new pull request without the suspend/resume handling?

Could you clarify how you think this should be fitting in the cpuidle
framework? This is system-wide S2/S3/S5 states we are talking about
here, and that comes with specific constraints, like moving code from
DRAM execution to SRAM execution for instance, not sure where cpuidle
can help with that. And if it does, how we coordinate with that framework.

There are some large portions of this code that are shared between SoCs,
past, current and future chips, with the exception of the small assembly
part which needs to be architecture specific for obvious reasons.

For instance, the power state machine code is fairly SoC-independant,
and to some extent, the DDR controller code is as well, that is what
motivated putting that code here, so it can be re-used in the future
when we submit support for new chips as well.

Ok, that one is one me, I should have made sure it was.

I can do that, but then I am really expecting someone to take a deep
look at the implementation and make some educated recommendations about
how this should be pieced together to achieve the expected ACPI-like
suspend states.

Ok, I see. So probably not cpuidle then, but I'd still have a better
feeling if this was reviewed by someone who understands power management
and is outside of the brcmstb team.

Maybe just send it to linux-pm to get feedback from the suspend maintainers?

Maybe drivers/firmware/broadcom/ then? That directory already
exists and the main parts seem to be for a firmware interface.

The DDR controller stuff probably better fits into drivers/memory/,
which already has similar bits from other platforms. Of course
that implies restructuring the code a bit to separate the two.

I should have been clearer with my complaint last week. I really mean both
of Brian's patches should be removed, although I mainly talked about the
other one. This patch goes to great length to introduce a soc_is_brcmstb()
function, but I'd rather see this never being used anywhere.

Drivers should not have to check the compatible property of the root node
(in some cases we do, but that is because the initial binding was broken
and we could not change it).

I've merged all of the series anyway, since it's not a big enough
problem to make you do another iteration, and I've already pushed
back once.

Let's talk about this again when you add users of this function, so
we can ideally come up with a better solution and remove the two files
again.

Pulled into next/soc. Thanks for your patience and for respinning
the series so quickly!

I admit I did not quite understand your initial comment was about both
patches, look back at this, the biuctrl code really does not need this
soc_is_brcmstb() thing at all, since it matches its own compatible
strings... whoops.
