This converts the mcp23s08 driver to be able to be used with
device tree.
There is a "spi-present-mask" device tree property, that allows to
use multiple of this spi chips on the same chipselect.
v4:
- removed the ability to specify the pullup from device tree
- updated binding doc
v3:
- removed mcp,chips device tree property in favour of a
mcp,spi-present-mask and a flag for the pullup of every gpio
- seperated the match table. Now there is one for i2c and one for spi
- do the of reading stuff on stack of the probe function - no devm
any more
v2:
- squashed booth patches together
- fixed build warning, when CONFIG_OF is not defined
- use of_match_ptr macro for of_match_table

gpio/omap: force restore if context loss is not detectable
When booting with device-tree the function pointer for detecting context
loss is not populated. Ideally, the pm_runtime framework should be
enhanced to allow a means for reporting context/state loss and we could
avoid populating such function pointers altogether. In the interim until
a generic non-device specific solution is in place, force a restore of
the gpio bank when enabling the gpio controller.
Adds a new device-tree property for the OMAP GPIO controller to indicate
if the GPIO controller is located in a power-domain that never loses
power and hence will always maintain its logic state.

gpio/omap: optimise interrupt service routine
The OMAP GPIO interrupt service routine is checking each bit in the
GPIO interrupt status register to see which bits are set. It is not
efficient to check every bit especially if only a few bits are set.
Therefore, instead of checking every bit use the __ffs() function,
which returns the location of the first set bit, to find all the set
bits.
This optimisation was suggested-by and developed in collaboration
with Felipe Balbi.

Pull EDAC fixes and ghes-edac from Mauro Carvalho Chehab:
"For:
- Some fixes at edac drivers (i7core_edac, sb_edac, i3200_edac);
- error injection support for i5100, when EDAC debug is enabled;
- fix edac when it is loaded builtin (early init for the subsystem);
- a "Firmware First" EDAC driver, allowing ghes to report errors via
EDAC (ghes-edac).
With regards to ghes-edac, this fixes a longstanding BZ at Red Hat
that happens with Nehalem and Sandy Bridge CPUs: when both GHES and
i7core_edac or sb_edac are running, the error reports are
unpredictable, as both BIOS and OS race to access the registers. With
ghes-edac, the EDAC core will refuse to register any other concurrent
memory error driver.
This patchset moves the ghes struct definitions to a separate header
file (include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to
register/unregister and to report errors via ghes-edac. Those changes
were acked by ghes driver maintainer (Huang)."

Fix mis-merge of intel_powerclamp.c resulting in compile error
The new intel_powerclamp thermal cooling device driver was merged in
commit
2af78448fff6 (Pull thermal management updates from Zhang Rui)
without any data conflicts. But there was a more subtle conflict I
missed: the driver uses MAX_USER_RT_PRIO, but commit
8bd75c77b7c6
("sched/rt: Move rt specific bits into new header file") had moved that
define from <linux/sched.h> to <linux/sched/rt.h>.
Which caused this build failure:
drivers/thermal/intel_powerclamp.c: In function ‘clamp_thread’:
drivers/thermal/intel_powerclamp.c:360:21: error: ‘MAX_USER_RT_PRIO’ undeclared (first use in this function)
drivers/thermal/intel_powerclamp.c:360:21: note: each undeclared identifier is reported only once for each function it appears in
And because I don't do a full "make allmodconfig" build after each pull,
I didn't notice until too late. So now the fix is here, separately from
the merge commit.

Pull ARM SoC mvebu platform changes from Olof Johansson:
"This series contains changes for the Marvell EBU platforms (mvebu,
orion, kirkwood, dove) that were not part of the first set of pull
requests because of dependencies on the MMC tree, and being submitted
a little late.
Notable changes are:
- More devices get moved out of board files into device tree
descriptions. The remaining devices listed in there have patches
that will get sent for 3.10, after which we can remove a lot of the
board files entirely. We are doing the pinctrl and mmc drivers
here, ethernet and PCI still remain.
- SMP support for mvebu is improved with support for the local
interrupt controller.
- The Guruplug board file gets replaced with a DT description.
Unfortunately, the dependency on the MMC tree turned out to be a much
larger problem than expected, when the MMC maintainer rebased the
patches in his tree that all of the patches in this branch are based
on, which caused merge conflicts between the new and old versions of
those patches.
To work around the merge conflicts, this branch rebases all patches on
top of the respective MMC patches that did get merged into 3.9. The
patches are all identical to the versions that were part of
linux-next, but have a new commit date."
