[PATCH 0/7] Various OF fixes for little-endian and ARM

[PATCH 0/7] Various OF fixes for little-endian and ARM

[Rob Herring]

From: Rob Herring <rob.herring-bsGFqQB8/DxBDgjK7y7TUQ@public.gmane.org>

This is a mixture of driver fixes for OF on little-endian and ARM platforms.

The last 2 patches need more thought. Currently, it's just copied from PPC. There 
are some ARM platforms which set 64-bit dma_masks (iop13xx and orion5x)
which is not handled. I would think 64-bit PPC would have a similar issue.

Rob Herring (7):
  OF: make drivers depend on CONFIG_OF instead of CONFIG_PPC_OF
  of: Fixes for OF probing on little endian systems
  ipmi: explicitly include of_address.h and of_irq.h
  mmc: sdhci-of: fix build on non-powerpc platforms
  mmc: sdhci-of: support generic OF controllers
  ARM: add dma_mask to pdev_archdata
  OF: set dma_mask for ARM

[PATCH 1/7] OF: make drivers depend on CONFIG_OF instead of CONFIG_PPC_OF

[Rob Herring]

From: Rob Herring <rob.herring-bsGFqQB8/DxBDgjK7y7TUQ@public.gmane.org>

Some OF drivers could likely be used on non-powerpc OF based platforms,
so fix the kconfig depends to be CONFIG_OF instead of CONFIG_PPC_OF

Hi Rob,

Which of these drivers are you actually using, or going to use in the
near future?

OLPC will probably use SDHCI soon, on an ARM system with Open Firmware 
in the boot FLASH.

And have you made sure that you haven't broken the allmodconfig builds on
other architectures that enable CONFIG_OF?

In general, is there an easy way to do this?  I can easily see a
difficult to bound testing
problem here, that might benefit from a build farm.

I can put it in my experimental branch that gets picked up by the
build server that ozlabs maintains.  However, having some level of
sanity checking beforehand is important before I do so.  Including a
log of what testing has been performed in the patch description is
always the right thing to do.

Well no as I don't have compilers for other arch's. The main OF platform 
to test here would be sparc as most of the kconfig options changed here 
already depend on PPC || MICROBLAZE.

I could simply have tacked on "|| ARM", but that seemed like the wrong 
thing to do. So I went down the path of looking at all OF drivers that 
could be used on other arch's.

Don't suppose you've got a set of powerpc host toolchains kicking
around too?  :-)

Nack on this hunk.  of_platform_drivers are now deprecated and the
regular platform_driver should be used instead.  Instead of extending
the of_platform_driver usage to all the architectures, please move the
of_match_table and the probe/remove routines into the platform_driver.

Okay, no problem. How do I get the match ptr or more importantly the 
data ptr from the match table? Do I have to call of_match_device within 
probe func?

[PATCH 2/7] of: Fixes for OF probing on little endian systems

[Rob Herring]

From: Rob Herring <rob.herring-bsGFqQB8/DxBDgjK7y7TUQ@public.gmane.org>

Fixes for sdhci-of and ipmi drivers.

Auditing all drivers using of_get_property did not find other
occurrences likely to be used on LE platforms.

Hmmm, I don't know what happened there, but I've re-merged it now and
it will appear in my public tree after I run through sanity testing.

I don't want to start a long debate, but is updating a kernel without 
updating the dtb really something to worry about? Isn't a year enough of 
a transition period.

Do these machines have a machine level compatible property that could be 
used instead?

Yes, once a .dtb is merged we try very hard not to break it.  It may
need to be updated to enable more features, but the goal is to not
regress.  One of the reason being that firmware may provide a default,
but old, dtb and it is important to still be able to boot on those
systems, even if the dtb is immediately going to be updated.

That's one of the reasons why it is so important to document and
review bindings up front and make sure they make sense before we
commit to them.

That being said, there are other ways to deal with old dtbs, like
fixing up the data at platform setup time.

[PATCH 5/7] mmc: sdhci-of: support generic OF controllers

[Rob Herring]

From: Rob Herring <rob.herring-bsGFqQB8/DxBDgjK7y7TUQ@public.gmane.org>

The base sdhci driver requires a valid ops struct. Add empty struct to
sdhci-of to allow generic controllers which don't need custom ops functions.

For the sdhci-patches, you should add linux-mmc@vger.kernel.org to the CC-list.
Done now...

[PATCH 7/7] OF: set dma_mask for ARM

[Rob Herring]

From: Rob Herring <rob.herring-bsGFqQB8/DxBDgjK7y7TUQ@public.gmane.org>

Various drivers require dma_mask to be valid, so it needs to be setup
when doing OF probing on ARM.

I'll let patches 6 & 7 lay fallow for the moment.  I'm not hugely fond
of the powerpc approach (which microblaze copies), but I haven't had a
chance to look for a better solution.

Looking at this some more, there's a couple of options I see.

Other buses (ISA, PCI, EISA) have a dma_mask in their struct. So perhaps 
platform_device should just have a dma_mask field.

There are several examples of setting dma_mask = &coherent_dma_mask. I'm 
not sure if this is considered correct. At least on ARM, I don't think 
these would need to be different.

Another option would be using bus notifiers to set the dma_mask like 
platform_data. But that doesn't seem like a good long term solution.

I think you need to change the order of these patches so that the fixes
for the bugs exposed by allowing the building of these drivers on other
platforms are before the patch that allows the building.
