Add support for the A4MP power domain, and hook up the HDMI-Link and FSI
hardware blocks.
This domain also contains the SPU2, FMSI, and BBIF2 hardware blocks,
but these are currently not used by any driver.

Note: As the default PM QoS latency constraint for SDHI is only 100 µs

constraint"), while DEFAULT_DEV_LATENCY_NS is 250000, suspend fails with
-EBUSY, unless the constraint is increased first to more than 500 µs

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)
- Using pr_*() macros more consistently instead of printk(KERN_*) in
some platform code"

The Kconfig symbol ARCH_HAS_OPP became redundant in v3.16: commit
049d595a4db3 ("PM / OPP: Make OPP invisible to users in Kconfig")
removed the only dependency that used it. Setting it had no effect
anymore.
So commit 78c5e0bb145d ("PM / OPP: Remove ARCH_HAS_OPP") removed it. For
some reason that commit did not remove all select statements for that
symbol. These statements are now useless. Remove one from shmobile too.

According to the datasheet, the operating clock for IIC0 is the HPP
(RT Peri) clock, not the SUB (Peri) clock. Both clocks run at the same
speed (50 Mhz).
This is consistent with IIC0 being located in the A4R PM domain, and
IIC1 in the A3SP PM domain.

This clock drives the irqpin controller modules.
Before, it was assumed enabled by the bootloader or reset state.
By making it available to the driver, we make sure it gets enabled when
needed, and allow it to be managed by system or runtime PM.

On sh73a0/kzm9g-legacy, probing of the i2c masters fails with:
i2c-sh_mobile i2c-sh_mobile.0: timing values out of range: L/H=0x208/0x1bf
sh_mobile: probe of i2c-sh_mobile.0 failed with error -22
According to the datasheet, the transfer rate is derived from the HP
clock (which runs at 104 MHz) divided by two. Hence
i2c_sh_mobile_platform_data.clks_per_count should be set to two.
Now probing succeeds, and i2c works:
i2c-sh_mobile i2c-sh_mobile.0: I2C adapter 0 with bus speed 100000 Hz (L/H=0x104/0xe0)

Commit "drm/rcar-du: Use struct videomode in platform data" touches board code

conflict for v3.18. Simon, are you fine with getting those changes merged
through Dave's tree (and could you confirm that no conflict should occur) ?

Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).
Specifics:
- Rework the handling of wakeup IRQs by the IRQ core such that all of
them will be switched over to "wakeup" mode in suspend_device_irqs()
and in that mode the first interrupt will abort system suspend in
progress or wake up the system if already in suspend-to-idle (or
equivalent) without executing any interrupt handlers. Among other
things that eliminates the wakeup-related motivation to use the
IRQF_NO_SUSPEND interrupt flag with interrupts which don't really
need it and should not use it (Thomas Gleixner and Rafael Wysocki)
- Switch over ACPI to handling wakeup interrupts with the help of the
new mechanism introduced by the above IRQ core rework (Rafael Wysocki)
- Rework the core generic PM domains code to eliminate code that's
not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during enumeration
(Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
- Add debugfs-based mechanics for debugging generic PM domains
(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in the
METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot (or
after resume from system suspend) and rework the ACPI Smart Battery
Subsystem (SBS) driver to work correctly with Apple platforms
(Matthew Garrett and Andreas Noever).
- ACPI LPSS (Low-Power Subsystem) driver update cleaning up the code,
adding support for 133MHz I2C source clock on Intel Baytrail to it
and making it avoid using UART RTS override with Auto Flow Control
(Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak)
- New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin)
- Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
Sudip Mukherjee, Yijing Wang, and Zhang Rui)
- cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
Rasmus Villemoes)
- cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name change
among other things), ppc-corenet, powernv (Viresh Kumar, Preeti U
Murthy, Shilpasri G Bhat, Lucas Stach)
- cpuidle support for DT-based idle states infrastructure, new ARM64
cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi, Rasmus
Villemoes)
- ARM big.LITTLE cpuidle driver updates: support for DT-based
initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
Kevin Hilman)
- Rework of the test_suspend kernel command line argument and a new
trace event for console resume (Srinivas Pandruvada, Todd E Brandt)
- Second attempt to optimize swsusp_free() (hibernation core) to make
it avoid going through all PFNs which may be way too slow on some
systems (Joerg Roedel)
- devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
- rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS entry
update in MAINTAINERS (Heiko Stübner, Kevin Hilman)
- PM core fix related to clock management (Geert Uytterhoeven)
- PM core's sysfs code cleanup (Johannes Berg)"

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.
Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.
Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.
