[GIT PULL] at91: drivers for 3.3

[Nicolas Ferre]

Arnd, Olof,

This is a first "drivers" part of our material for 3.3 merge window. It collects
Ethernet drivers changes.
One thing to note is that the macb.c driver is modified to support
device tree. We agreed with David to drag those modifications into
arm-soc git tree because they go on top of Jamie's work on macb-gem driver
already in your drivers/macb-gem branch.

This pull request goes on top of Linus' 3.2-rc5 commit but with additional 
dependencies with two of your branches:
1/ fixes (which seems already included in 3.2-rc5)
2/ drivers/macb-gem

I had to resolve a conflict while merging the macb-gem branche with current 3.2-rc5. The 
resolution is commited into this branch.
Tell me if you need more precision.


The following changes since commit 6d69370e2b4a1e04e9ba0095d60aec7736fa1a99:

  Merge remote-tracking branch 'armsoc/drivers/macb-gem' into for-3.3on32rc5-drivers (2011-12-15 15:55:59 +0100)

The history of this branch due to the double dependencies gets a bit
awkward. Also, it seems like you in one of your merges kept the
'default y' in NET_CADENCE that should have been removed.

Would you mind trying this instead?

* Base this new branch on the previous macb-gem branch
* Cherry-pick the fixes from 'fixes' into the new branch if truly
needed -- I tested here and all of the patches applied cleanly.
* Then apply these patches
* For build testing before sending, merge into for-next to aggregate
with the rest of the 'fixes' changes -- it's OK that we have to do a
fixup here.

That should give a clean branch with neat history for just these
changes. About 'fixes': Since they are in for-next, and will be in
3.2, that dependency will be taken care of that way.

Then send a fresh pull request for that new branch, please.


Thanks!

Well, no, this line has been added into "eccab1ec" and is in mainline
since 3.2-rc3.

This line have to be kept and the merge conflict is triggered during the
merge of macb-gem on top of Linus' tree. BTW, this merge is already
performed properly in linux-next.

Ok, I will base my "drivers" branch on top of macb-gem one and send you
another pull request.

Pulled into next/drivers, thanks for the quick update!

This patch breaks build for non-OF configs. I hit this at least with
afeb9260_defconfig, at91cap9_defconfig and at91sam9263_defconfig.
Still building other defconfigs:

drivers/net/ethernet/cadence/macb.c:1503: error: implicit declaration
of function 'of_match_ptr'
drivers/net/ethernet/cadence/macb.c:1503: error: 'macb_dt_ids'
undeclared here (not in a function)
drivers/net/ethernet/cadence/macb.c:1503: error: initializer element
is not constant
drivers/net/ethernet/cadence/macb.c:1503: error: (near initialization
for 'macb_driver.driver.of_match_table')
