[PATCH 0/3] arm: fix build breakage in omap2plus_defconfig (linux-next)

[PATCH 0/3] arm: fix build breakage in omap2plus_defconfig (linux-next)

[Paul Gortmaker]

I decided to look at why this thing was dying in linux-next for
over two weeks now:

http://kisskb.ellerman.id.au/kisskb/target/5581/

The git bisect led me to sfr's merge (661a40a5c8 in March5th tree)
of 'arm-soc/for-next' but there was nothing suspicious there, and
the fix (commit #1) was reasonably obvious, so I didn't investigate
the root cause further.  But that wasn't where the breakage ended...

Commit #2, and especially commit #3 need to be looked at by those
who know the platform.  It looks like some sort of conversion to
better share code was done, but the omap4panda part didn't get
the full attention it needed.  I did what I think looks right,
based on what was done for the other board, but I've no knowledge
of the platform whatsoever, and hence no confidence it would
work as desired.  I've hopefully put the right people on the CC
list for those.

Paul.

[PATCH 1/3] arm: anticipate build breakages due in pending merge

[Paul Gortmaker]

Testing in linux-next has revealed that the omap2plus_defconfig
will fail upon the merge of "arm-soc/for-next" as follows:

arch/arm/mach-omap2/control.c:238: error: 'OMAP343X_CTRL_BASE' undeclared (first use in this function)

arch/arm/mach-omap2/cm2xxx_3xxx.c:310: error: 'OMAP3430_CM_BASE' undeclared (first use in this function)

It appears that a once implicit path to <plat/hardware.h> has gone
away once two of the arm streams come together.

[PATCH 2/3] arm: fix compile error in mach-omap2/board-omap4panda.c

[Paul Gortmaker]

The commit 3c90c98a1ebbb08d95700ce8a3b7bce6286607bd (linux-next)

    "OMAP4: omap4panda: Enable audio support"

introduced population of a new struct, but chose the wrong (but
similarly named) struct that has none of the named fields.

Change it to the struct with those fields, to fix:

arch/arm/mach-omap2/board-omap4panda.c:284: error: unknown field 'hs_left_step' specified in initializer
arch/arm/mach-omap2/board-omap4panda.c:285: error: unknown field 'hs_right_step' specified in initializer

[PATCH 3/3] arm: more fallout from i2c conversions in board-omap4panda.c

[Paul Gortmaker]

Commit ded0df8510778a03a2f182a0cbfe3c25788e8852 (linux-next)

   "mfd: Convert twl6040 to an i2c driver, and separate it from twl core"

appears to have done an incomplete conversion on the board-omap4panda.c
file, leaving it with more build failures.  Comparing the changes that
were done for board-4430sdp.c it is possible for me to whack it with a
stick until it stops twitching, but someone who really understands this
code needs to take a look at the conversion, and check it is done
completely and in a way that will actually work on hardware.

Thanks this one is already waiting to be applied to arm-soc
tree.

Thanks, this mis-merge is something Peter should take a look at
as it seems there's few other parts that got left out.

Yes, I have also noticed it.
This is because part of the twl6040 i2c conversion series has been taken
by Samuel.
He will stop carrying it further (I hope), and we are going to have a
bit different series going via audio.
Samuel did not took the panda part of the patches since it had some
other dependencies coming via audio tree.

The thing is that the panda audio support is coming via ASoC to
linux-next, so Samuel could not take the patch addressing this breakage
(mfd tree does not have the needed patches).

I'm not sure where we could apply this patch in the first place since
mfd does not have the panda audio support patches, and currently the
ASoC does not have the twl6040 i2c conversion patches either...

This is true.
I'm sending a revert series for the twl6040 patches causing this
breakage for Samuel.
The same feature will go via audio tree because the dependencies are
queued in that feature tree.

PS: this might fix the compile breakage with omap2_defconfig, but the
audio will not work if you enable the support for it on OMAP4.
