This is the complete Ux500 multiplatform patchset.
The only thing missing is a few ACKs from the MFD
maintainer (Samuel Ortiz).
Arnd Bergmann (7):
ARM: ux500: move mach/msp.h to <linux/platform_data/*>
staging: ste_rmi4: kill platform_data hack
ARM: ux500: split out prcmu initialization
ARM: ux500: make irqs.h local to platform
ARM: ux500: make remaining headers local
ARM: ux500: move to multiplatform
ARM: ux500: build hotplug.o for ARMv7-a
Linus Walleij (7):
ARM: ux500: move debugmacro to debug includes
clk: ux500: pass clock base adresses in init call
mfd: prcmu: pass a base and size with the early initcall
mfd: db8500-prcmu: get base address from resource
ARM: ux500: move PM-related PRCMU functions to machine
ARM: ux500: make debug macro stand-alone
ARM: ux500: get rid of <mach/[hardware|db8500-regs].h>

This moves the Ux500 debug macro to the debug headers to
make way for multiplatform support.

The ux500 clock driver was including <mach/db8500-regs.h>
which will not work when building for multiplatform support
since <mach/*> is going away.
Pass the base adresses in the init call instead.

From: Arnd Bergmann <arnd@arndb.de>
There is only one instance of the platform data for synaptics_i2c_rmi4
in the mainline kernel, so there is no point of pretending its
variable here. The only member that has a dependency on the platform
is actually the interrupt number, and there is a field in the
i2c_client structure that gets initialized from the board info,
so we can trivially move the board_into into the platform without
knowledge of the platform_data structure.

From: Linus Walleij <linus.walleij@linaro.org>
This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.

We cannot use a global variable stored in <mach/hardware.h> to
find the base address of the PRCMU. The real resource is already
there from the board, so use this to look up the base address
instead.
Currently the patch is kept minimal so as not to interfere with
other work being done on refactoring this driver, but at a later
point the defines using (prcmu_base + 0xnnn) need to be replaced
by pure offset defined for (0xnnn) and the base inlined with the
readl()/writel() and similar codepaths.

From: Linus Walleij <linus.walleij@linaro.org>
We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.
Basically we are left with the two alternatives of code
placement as:
- arch/arm/mach-ux500/pm.c - this because the code is
closely related to the GIC, and takes ownership of
some of the registers from the PRCMU related to this
PM functionality.
- drivers/mfd/db8500-prcmu-pm.c - because the code is
affecting stuff in the PRCMU register range. But then
this code needs to remap and handle GIC registers.
This patch implementation is taking the first approach.
Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.
The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

Sam, I'm requesting an ACK for taking this through the
ARM SoC tree.

This pushes the knowledge of physical addresses down into
the debug macro so we can get rid of the <mach/hardware.h>
dependency.

From: Linus Walleij <linus.walleij@linaro.org>
This removes <mach/hardware.h> and <mach/db8500-regs.h>
from the Ux500, merging them into the local include
"db8500-regs.h" in mach-ux500. There is some impact
outside the ux500 machine, but most of it is dealt with
in earlier patches.
Contains portions of a clean-up patch from Arnd Bergmann.

ChangeLog v1->v2:
- Remove erroneous hunk adding the GIC distbase as resource
to the PRCMU. This was done away with in the previous patch.
- Split debug-macro portions into a separate patch.
Sam: seeking your ACKs to take this through ARM SoC.

To: linux-arm-kernel
From: Arnd Bergmann <arnd@arndb.de>
This untangles the final bits of the prcmu code from the platform
code:
* The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c
because they are only of local significance.
* u8500_thsens_device goes into the prcmu, because it uses a PRCMU
IRQ that the platform does not see.
* IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data
because the PRCMU does not see it.

With the PRCMU out of the way, nothing outside of mach-ux500
uses mach/irqs.h any more, so we can make it a local header file,
including the two sub-headers.

mach/setup.h and mach/devices.h are only needed from inside of mach-ux500
now, so we can simply move them out of the include/mach directory.

Nothing is holding us up any more, and we can make ux500 coexist
with the rest of the platforms. The timex.h and uncompress.h
headers are no longer needed now.

If we try to build this file in a multiplatform configuration with
ARMv6 enabled, gas complains about the dsb operation being undefined.
Adding -march=armv7-a is safe because that code is only ever run
on ux500, which is Cortex-A9.

Ok, very nice!
I'd like to put them into arm-soc really soon to give it some
more time in linux-next before the merge window, but I don't
want to step on Sam's toes here.
Sam, can you send an ACK or NAK by Monday? If I don't hear back
from you, I'll put it into arm-soc as is, and we'll have to address
any further comments with add-on patches.

Acked-by: Samuel Ortiz <sameo@linux.intel.com> for the 4 patches.
I am fine with Linus' changes. Would it be possible for you to setup a branch
where I could also pull those changes from ? Or are the interdependencies too
strong to do so ?
I'd like to avoid potential conflicts as much as possible...
Cheers,
Samuel.

Sure, I always create a stable branch for each pull request I get for this
purpose anyway. Actually it might be nice if Linus could produce two branches:
One that has the MFD changes only, and the second one based on the first that
adds all the remaining changes. Then you can pull in just the first branch
and don't need to add too many changes outside of drivers/mfd to your tree.
I don't think that the patches depend on anything that is already in arm-soc,
but we might need to add other changes on top.

That would be ideal, yes.
Cheers,
Samuel.
