Pull irq domain updates from Thomas Gleixner:
"The real interesting irq updates:
- Support for hierarchical irq domains:
For complex interrupt routing scenarios where more than one
interrupt related chip is involved we had no proper representation
in the generic interrupt infrastructure so far. That made people
implement rather ugly constructs in their nested irq chip
implementations. The main offenders are x86 and arm/gic.
To distangle that mess we have now hierarchical irqdomains which
seperate the various interrupt chips and connect them via the
hierarchical domains. That keeps the domain specific details
internal to the particular hierarchy level and removes the
criss/cross referencing of chip internals. The resulting hierarchy
for a complex x86 system will look like this:
vector mapped: 74
msi-0 mapped: 2
dmar-ir-1 mapped: 69
ioapic-1 mapped: 4
ioapic-0 mapped: 20
pci-msi-2 mapped: 45
dmar-ir-0 mapped: 3
ioapic-2 mapped: 1
pci-msi-1 mapped: 2
htirq mapped: 0
Neither ioapic nor pci-msi know about the dmar interrupt remapping
between themself and the vector domain. If interrupt remapping is
disabled ioapic and pci-msi become direct childs of the vector
domain.
In hindsight we should have done that years ago, but in hindsight
we always know better :)
- Support for generic MSI interrupt domain handling
We have more and more non PCI related MSI interrupts, so providing
a generic infrastructure for this is better than having all
affected architectures implementing their own private hacks.
- Support for PCI-MSI interrupt domain handling, based on the generic
MSI support.
This part carries the pci/msi branch from Bjorn Helgaas pci tree to
avoid a massive conflict. The PCI/MSI parts are acked by Bjorn.
I have two more branches on top of this. The full conversion of x86
to hierarchical domains and a partial conversion of arm/gic"

Pull asm-generic asm/io.h rewrite from Arnd Bergmann:
"While there normally is no reason to have a pull request for
asm-generic but have all changes get merged through whichever tree
needs them, I do have a series for 3.19.
There are two sets of patches that change significant portions of
asm/io.h, and this branch contains both in order to resolve the
conflicts:
- Will Deacon has done a set of patches to ensure that all
architectures define {read,write}{b,w,l,q}_relaxed() functions or
get them by including asm-generic/io.h.
These functions are commonly used on ARM specific drivers to avoid
expensive L2 cache synchronization implied by the normal
{read,write}{b,w,l,q}, but we need to define them on all
architectures in order to share the drivers across architectures
and to enable CONFIG_COMPILE_TEST configurations for them
- Thierry Reding has done an unrelated set of patches that extends
the asm-generic/io.h file to the degree necessary to make it useful
on ARM64 and potentially other architectures"

Pull ARM SoC/OMAP GPMC driver cleanup and move from Arnd Bergmann:
"The GPMC driver has traditionally been considered a part of the OMAP
platform code and tightly interweaved with some of the boards.
With this cleanup, it has finally come to the point where it makes
sense to move it out of arch/arm into drivers/memory, where we already
have other drivers for similar hardware. The cleanups are still
ongoing, with the goal of eventually having a standalone driver that
does not require an interface to architecture code.
This is a separate branch because of dependencies on multiple other
branches, and to keep the drivers changes separate from the normal
cleanups"

Pull ARM SoC cleanups from Arnd Bergmann:
"The remaining cleanups for 3.19 are to a large part result of
devicetree conversion nearing completion on two other platforms
besides AT91:
- Like AT91, Renesas shmobile is in the process to migrate to DT and
multiplatform, but using a different approach of doing it one SoC
at a time. For 3.19, the r8a7791 platform and associated "Koelsch"
board are considered complete and we remove the non-DT
non-multiplatform support for this.
- The ARM Versatile Express has supported DT and multiplatform for a
long time, but we have still kept the legacy board files around,
because not all drivers were fully working before. We have finally
taken the last step to remove the board files.
Other changes in this branch are preparation for the later branches or
just unrelated to the more interesting changes:
- The dts files for arm64 get moved into per-vendor directories for a
clearer structure.
- Some dead code removal (zynq, exynos, davinci, imx)

Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann:
"On Atmel AT91, the conversion to device tree is now considered
complete, and all machines that were not already converted in 3.18 are
assumed to be unused and dropped by the maintainer.
All remaining board files that were written in C are dropped, and the
ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
altogether. Cleaning up the last pieces was great fun, so I took the
time to do some of the coding myself and removed several hundred code
lines that ended up unused after the board files were done.
There are still a couple of AT91 specific device drivers that are not
converted to DT (CF, USB-OTG) and currently not working, and the
platform itself is not "multiplatform"-enabled, but both issues are
going to be taken care of in the 3.20 cycle.

This will enable use of physical arch timers on rk3288, where each
core comes out of reset with a different virtual offset. Using
physical timers will help with SMP booting on coreboot and older
u-boot and should also allow suspend-resume and cpu-hotplug to work on
all firmwares.
Firmware which does initialize the cpu registers properly at boot and
cpu-hotplug can remove this property from the device tree.

This is a bug fix for using physical arch timers when
the arch_timer_use_virtual boolean is false. It restores the
arch_counter_get_cntpct() function after removal in
0d651e4e "clocksource: arch_timer: use virtual counters"
We need this on certain ARMv7 systems which are architected like this:
* The firmware doesn't know and doesn't care about hypervisor mode and
we don't want to add the complexity of hypervisor there.
* The firmware isn't involved in SMP bringup or resume.
* The ARCH timer come up with an uninitialized offset between the
virtual and physical counters. Each core gets a different random
offset.
* The device boots in "Secure SVC" mode.
* Nothing has touched the reset value of CNTHCTL.PL1PCEN or
CNTHCTL.PL1PCTEN (both default to 1 at reset)
One example of such as system is RK3288 where it is much simpler to
use the physical counter since there's nobody managing the offset and
each time a core goes down and comes back up it will get reinitialized
to some other random value.

The imx6 PM code seems to be quite creative in its use of irq_data,
using something that is very much a hardware interrupt number where
we expect a virtual one. Yes, it worked so far, but that's only
luck, and it will definitely explode in 3.19.
Fix it by using a pair of helper functions that deal with the
actual hardware.

mach-imx directly references to the irq field in
struct irq_data, and uses this to directly poke hardware register.
But irq is the *virtual* irq number, something that has nothing
to do with the actual HW irq (stored in the hwirq field). And once
we put the stacked domain code in action, the whole thing explodes,
as these two values are *very* different.
Just replacing all instances of irq with hwirq fixes the issue.

based SoCs
This patch enables the MAX77686 PMIC drivers in the multi_v7_defconfig used
on exynos4412-prime family of SoCs [1]. The exynos4412-prime based boards
are producing the following runtime errors only on the multi_v7_defconfig [2]:
kern.err: deviceless supply vdd_arm not found, using dummy regulator
kern.err: exynos-cpufreq exynos-cpufreq: failed to set cpu voltage to 1287500
kern.err: cpufreq: __target_index: Failed to change cpu frequency: -22
I reviewed the exynos_defconfig, which does not produce these runtime
errors. It was obvious that the exynos_defconfig has the PMIC drivers
enabled, whereas the multi_v7_defconfig does not. This patch has been tested
on a odroid-u2 and a odroid-u3 board. It has resolved the runtime errors.
Therefore, I purpose we enabled these drivers in the multi_v7_defconfig.
