[PATCH 00/16] Orion DT conversions and fixes.

[PATCH 00/16] Orion DT conversions and fixes.

[Andrew Lunn]

This is a collection of patches converting more drivers used by orion
to DT. Then, where possible, convert platform code to use DT. Also
a few fixes are mixed in.

- IRQ/GPIO/SPI/WDT/SATA have all been seen before and no changes made.
- I2C has been split in two, with the driver parts now going via
  i2c-embedded/for-next
- gpio-key and gpio-led converted to DT equivalents.
- Ensure runit clock always ticks is a rework of an earlier patch, now
  including comments from Marvell engineers.
- Replace mrvl with marvell implements the decision made here:
  http://www.spinics.net/lists/arm-kernel/msg176524.html

These patches, plus the I2C driver change and all the patches i've
collected from others ready for submission to arm-soc/for-next can be
found in:

git://github.com/lunn/linux.git v3.5-rc7-for-next-v5 

Andrew Lunn (16):
  ARM: Orion: DT support for IRQ and GPIO Controllers
  SPI: Refactor spi-orion to use SPI framework queue.
  ARM: Kirkwood: Ensure runit clock always ticks.
  ARM: Orion: Add arch support needed for I2C via DT.
  Kirkwood: Add basic device tree support for QNAP TS219.
  ARM: Orion: DTify the watchdog timer.
  ATA: sata_mv: Add device tree support
  ARM: Kirkwood: Use DT to configure SATA device.
  ARM: Kirkwood: Describe DNS325 temperature sensor in DT.
  ARM: Kirkwood: Describe IB62x0 gpio-keys in DT.
  ARM: Kirkwood: Describe iConnects temperature sensor in DT.
  ARM: Kirkwood: Describe Dreamplug LEDs in DT.
  ARM: Kirkwood: Describe GoFlex Net LEDs and SATA in DT.
  ARM: Kirkwood: Describe ib62x0 LEDs in DT.
  ARM: Kirkwood: Describe iConnect LEDs in DT.
  ARM: Kirkwood: Replace mrvl with marvell

[PATCH 1/16] ARM: Orion: DT support for IRQ and GPIO Controllers

[Andrew Lunn]

Both IRQ and GPIO controllers can now be represented in DT.  The IRQ
controllers are setup first, and then the GPIO controllers. Interrupts
for GPIO lines are placed directly after the main interrupts in the
interrupt space.

[PATCH 2/16] SPI: Refactor spi-orion to use SPI framework queue.

[Andrew Lunn]

Replace the deprecated master->transfer with transfer_one_message()
and allow the SPI subsystem handle all the queuing of messages.

Send these with Mark Brown on the To: line right now, I think he's
busy collecting SPI patches for the next merge window.

Hi Linus, Mark and now Arnd.

I was planning sending all these via arm-soc. 

This patch is part of a bigger collection of Orion changes. The rest
are contributions from others which have already been ack-by, etc, on
the lists.

Somewhere near the beginning of this series is:

4385fbf SPI: Refactor spi-orion to use SPI framework queue.
d9d8293 spi-orion: remove uneeded spi_info
ee13b49 spi-orion: add device tree binding
76f0b84 ARM: kirkwood: use devicetree for SPI on dreamplug
05f504f ARM: kirkwood: use devicetree for orion-spi

You can see the chain of dependencies here. So at minimum i would need
to send the first three via Mark. I then need to cross my fingers and
hope he really picks them up, because without them, we are going to
have a number of boards which fail to find their root file system on
an SPI flash.

Now, maybe i've done all this wrong, since i'm a newbie to collecting
patches together for submission upstream....

You can see the complete set of patches here:

git://github.com/lunn/linux.git v3.5-rc7-for-next-v5

There is one exception and that is the very first patch:

I2C: MV64XXX: Add Device Tree support 

which Wolfram Sang insists goes via him. I see this less critical. If
for some reason it does not make it in, all it means is temperature
sensors and RTCs are missing, but at least the boards still boot.

	Andrew

Well, I'd like to think that generally I'm reasonably responsive to
patch submissions and obviously there's no great urgency here since
we're in the merge window - nothing is likely to go in until 3.7 anyway,
though it'd be handy if the DT updates went in early (and they're very
low risk...).

The general pattern with these things should be that the patches get
sent via the normal route and any unusual requirements discussed then.
To be honest it doesn't seem like there's much problem here, you've got
no build time dependencies or anything.

Well, this particular patch was first submitted May 19th and Ack-by
Linus on May 14th.

http://comments.gmane.org/gmane.linux.kernel.spi.devel/9937

It was reposted 10 Jun and Acked-by again in Jun 10 by Linus.

It was also reposted July 3.

None of which were CCed to me; they were all before I started looking
after SPI so that's not surprising but still the number of reposts is
more a comment on why I'm helping out here than on what I said above.

Hi Mark

O.K., fair enough.

Will you accept any patches for this merge window? As you said, the DT
enablement is low risk. It should be possible to separate this one
patch from the other two.

Can you send the patches please?

The bit I was saying was most low risk was the actual DT changes, as
opposed to the bits that parse and use the DT.

Would it not be better to just omit this if it doesn't do anything and
doesn't have any semantics defined?

I've applied this.  If you could send the other patches that'd be
helpful...

I was specifically asked to include this, which is why it appeared in
v2, not the first version. I forget who it was who asked for it, maybe
Arnd Bergmann? I can dig through my email archive if you want to know.

If you're going to include it you should define some sematics for it.
You could define an optional "yohNg1ai" property too...

Agreed. I'm rather sure I did not ask for an unused property to be
documented. However, the documentation should definitely match the
example and the what kinds of properties are used in the device tree.

If the device has an interrupt that is not used by Linux, I would
document what the interrupt is for.

I just sent the DT enabling patch. The other two, "Refactor spi-orion
to use SPI framework queue." and "remove uneeded spi_info" can wait
for the next merge window. For me, they are lower priority than
getting DT working.

Ah, O.K. I understood you wrongly. I actually think they are the most
dangerous part. A board booting with these DT changes, and without the
driver enablement for DT is likely to fail to find its root
filesystem.

Why would that be?  If there's no DT support for the driver it'll just
ignore the DT.

Yes, it ignores the DT. However, SPI driver never gets
instantiated. The FLASH chip on the SPI bus never gets
instantiated. MTD partitions are probably created, but since the
underlying device is missing, they don't work and the root filesystem
is not available.
 
There is no logic in the board code to first try DT, and if that
fails, use old fashioned platform_device instantiating of the drivers.

I've also had bad experiences when we have the old platform_device
instantiating plus DT also instantiating the same device.

The only way i've found to convert an existing board from
platform_device to DT is to first add DT support to the driver, and
then atomically swap platform_device structures for DT descriptions.

Well, I'd really expect this to be done the other way around.

Hopefully we can arrange for them to collide with each other...

I guess if it's not working then we need to do that, but it's really sad
that the DT deployment is this painful.

[PATCH 3/16] ARM: Kirkwood: Ensure runit clock always ticks.

[Andrew Lunn]

Marvell engineers tell us:

	It seems that many units use the RUNIT clock.
	SPI, UART, NAND, TWSI, ...
	So it's not possible to clock gate it.

Currently the SPI, NAND and TWSI driver will clk_prepaure_enable()
this clk, but since we have no idea what ... is, and turning this clk
off results in a hard lock, unconditionally enable runit.

[PATCH 5/16] Kirkwood: Add basic device tree support for QNAP TS219.

[Andrew Lunn]

The two different variants of QNAP TS devices, varying by SoC, put the
GPIO keys on different GPIO lines. Hence we need two different DT
board descriptions, which share the same board-ts219.c file.

Hi Arnaud

Still need my second coffee of the day.

Those patches never went to the list, as far as i remember. Please can

patchsets.

Thanks
