[PATCH 0/2] ARM: mvebu: Add support for SPI controller in Armada 370/XP

[Ezequiel Garcia]

Hi,

This patchset adds support for the SPI controller
available in Armada 370 and Armada XP SoC.

The patches are based in Jason Cooper's mvebu/dt branch.

Feel free to test and/or provide feedback.

Ezequiel,

This series looks good.  just a few comments:

It probably doesn't matter for this series (I haven't tried to apply it
yet), but please base future work off of a mainline tag (eg v3.8-rc6).
It makes merge conflicts easier to resolve.

Feel free to test-merge against the mvebu/ branches and let me know of
any conflicts.

Also, your patch series appears to be out of order, did you use git
send-email once per file?

thx,

Jason.

Ah, I see.

I was mistakenly assuming you wanted against that branch;
I'll base the patches on mainline in the future.

Thanks for the advice.

I always send the cover letter manually. This time I did it after the patches.
I'm in the process of automating this in my workflow,
but feel free to make a suggestion.

Nope, the branches are organized that way to sanely merge in with all
the other arm-soc code.  While I make every effort to keep them stable
(ie, not rebased), they may change at anytime if I need to fix things.

tags are stable, and if all patches are based on tags, then merge
conflicts follow a predictable pattern.  Anything else devolves into
chaos.

if format-patch is called properly (I know from experience how to call
it improperly ;-) ), you can just do

$ git send-email ... /path/to/patches/*.patch

and it'll get the order correct.  It will also ask for confirmation
before sending each email.

Dry-run sending a series just to yourself lets you see how it will
appear once it goes out to the list.

hth,

Jason.

Ahá... this explains why I was seeing your branches rebased! ;-)

Hi Ezequiel

Do any of the boards we have with mainline support have any devices on
the SPI busses? Its hard to test otherwise.

Mmm... very true.

Recently added Armada XP GP board as an SPI flash.
Probably other evaluation boards also has similar SPI flashes,
but I should check that.

I'll prepare a patch for GP board tomorrow,
based on Gregory's patches for that board,
so you can test that.
Also, I hope to prepare patches for the other
evaluation boards soon.

Currently the driver only use the 5th first register. All of the other
mvebu platform declare the last register at offset 0x28. The Armada
370 SoC have also the last register at offset 0x28. Only for the
Armada XP SoC there are more registers and we have a the last register
at offset 0x50. Obviously the driver won't use these extra register.

So I think that the best for now is to declare:
			reg = <0xd0010600 0x28>;
