Pull CMA and DMA-mapping updates from Marek Szyprowski:
"This time the pull request is rather small, because the further
redesign patches were not ready on time.
This pull request consists of the patches which extend ARM DMA-mapping
subsystem with support for CPU coherent (ACP) DMA busses. The first
client of the new version is HighBank SATA driver. The second part of
the pull request includes various cleanup for both CMA common code and
ARM DMA-mapping subsystem."
Fix up trivial add-add conflict due to the "dma-coherent" DT property
being added next to the "calxeda,port-phys" property for the Calxeda
AHCI controller.
* 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
ARM: dma-mapping: Remove unsed var at arm_coherent_iommu_unmap_page
ARM: highbank: add coherent DMA setup
ARM: kill off arch_is_coherent
ARM: add coherent iommu dma ops
ARM: add coherent dma ops
ARM: dma-mapping: Refrain noisy console message
ARM: dma-mapping: Small logical clean up

With many IOMMU'able devices, console gets noisy.
Tegra30 has a few dozen of IOMMU'able devices.

Some highbank DMA masters can support coherent (ACP) or non-coherent DMA.
This sets up dma_map_ops for masters which are configured for coherent DMA.

With ixp2xxx removed, there are no platforms that define arch_is_coherent,
so the last occurrences of arch_is_coherent can be removed. Any new
platform with coherent i/o should use coherent dma mapping functions.

arch_is_coherent is problematic as it is a global symbol. This
doesn't work for multi-platform kernels or platforms which can support
per device coherent DMA.
This adds arm_coherent_dma_ops to be used for devices which connected
coherently (i.e. to the ACP port on Cortex-A9 or A15). The arm_dma_ops
are modified at boot when arch_is_coherent is true.

Pull power management updates from Rafael J Wysocki:
- Improved system suspend/resume and runtime PM handling for the SH
TMU, CMT and MTU2 clock event devices (also used by ARM/shmobile).
- Generic PM domains framework extensions related to cpuidle support
and domain objects lookup using names.
- ARM/shmobile power management updates including improved support for
the SH7372's A4S power domain containing the CPU core.
- cpufreq changes related to AMD CPUs support from Matthew Garrett,
Andre Przywara and Borislav Petkov.
- cpu0 cpufreq driver from Shawn Guo.
- cpufreq governor fixes related to the relaxing of limit from Michal
Pecio.
- OMAP cpufreq updates from Axel Lin and Richard Zhao.
- cpuidle ladder governor fixes related to the disabling of states from
Carsten Emde and me.
- Runtime PM core updates related to the interactions with the system
suspend core from Alan Stern and Kevin Hilman.
- Wakeup sources modification allowing more helper functions to be
called from interrupt context from John Stultz and additional
diagnostic code from Todd Poynor.
- System suspend error code path fix from Feng Hong.
Fixed up conflicts in cpufreq/powernow-k8 that stemmed from the
workqueue fixes conflicting fairly badly with the removal of support for
hardware P-state chips. The changes were independent but somewhat
intertwined.

The programming model for P-states on modern AMD CPUs is very similar to
that of Intel and VIA. It makes sense to consolidate this support into one
driver rather than duplicating functionality between two of them. This
patch adds support for AMDs with hardware P-state control to acpi-cpufreq.

Add a "C5" cpuidle state to the SH7372 SoC connected to the A4S power
domain in such a way that A4S may be turned off by cpuidle if all
I/O devices in that domain have been suspended (or do not have
attached drivers).
This requires some reorganization of the initialization of SH7372
power management which affects the the boards based on it, Mackerel
and AP4EVB.

The sh7372 cpuidle code uses the same artificially designed routine
shmobile_cpuidle_enter() as the .enter() callback for all of its
cpuidle states. However, shmobile_cpuidle_enter() calls a different
"enter" function for each state using an array of function pointers
populated by the sh7372 PM initialization code. Moreover, the
states[] array of the shmobile cpuidle driver is populated by that
code as well, although in principle it just might have been filled
with static data.
All of that complexity goes away if the sh7372 cpuidle code is
allowed to define its own cpuidle driver structure that can be passed
for registration to the common shmobile cpuidle initialization
routine, so modify the code accordingly.

The role of the only function in the common.c file in
arch/arm/mach-shmobile, shmobile_init_late(), is to call two
initializers whose definitions depend on kernel configuration
options. Those initializers may very well be called from a static
inline function in arm/mach-shmobile/include/mach/common.h,
though, in which makes the code a bit easier to read. Moreover,
the common.c may be dropped entirely then.

The !console_suspend_enabled check in sh7372_enter_suspend() seems

Use the function rmobile_add_devices_to_domains() introduced
previously for adding devices to PM domains during the AP4EVB
initialization instead of a series of rmobile_add_device_to_domain*()
calls. This also causes the default device PM QoS latencies to be
used on that board in analogy with Mackerel.

On SH7372 and Mackerel devices are added to PM domains through a
series of rmobile_add_device_to_domain_td() calls where the last
argument is always the same. This is quite inefficient, so add
a common function for adding devices to PM domains that reads the
domain-device pairs information from a table and use it during SH7372
and Mackerel initialization.

The results of adaptive latency computations in
GENPD_DEV_TIMED_CALLBACK() show that the start/stop and save/restore
state latencies of all devices on the Mackerel board I have tried are
a little below 250 us. Therefore, if the 250 us is used as the
common initial value of the latency fields in struct gpd_timing_data
for all devices on Mackerel, the latency values will never have to
change at run time and there won't be any overhead related to
re-computation of the corresponding PM QoS data.

The sh7372_enter_suspend() routine checks the status field of the
generic PM domain object corresponding to the A4S domain in order to
check if it can turn that domain off when entering system sleep.
However, it shouldn't rely on the specific values of the generic
data structures this way, so make it use its own mechanism to
recognize when it is safe to turn that domain off.
For this purpos, introduce a boolean variable a4s_suspend_ready
that will be set by the A4S' suspend routine and unset by its
resume routine executed by rmobile_pd_power_down() and
__rmobile_pd_power_up(), respectively.

will be able to use rmobile_add_device_to_domain() for adding devices
to those domains and r8a7779_add_device_to_domain(), which is not
used anywhere at the moment anyway, may be dopped.
Accordingly, give names to the r8a7779's PM domains and drop
r8a7779_add_device_to_domain().

Make the power management code under arch/arm/mach-shmobile/ use
names of power domains instead of pointers to domain objects for
adding devices to the domains. This will allow us to put the
domain objects into tables and register them all in one shot
going forward.

Calxeda highbank SATA phy has intermittent problems bringing up a link
with Gen3 drives. Retrying the phy hard reset can work-around this issue,
but each reset also disables spread spectrum support. The reset function
also needs to reprogram the phy to enable spread spectrum support.
Create a new driver based on ahci_platform to support the Calxeda Highbank
SATA controller.

- Lots of error handling cleanups from Guenter Roeck
- Removal of the existing Tegra driver which is quite comprehensively
broken as detailed in the changelog for the removal.

Amend the PL022 pin controller to optionally take a pin control
handle and set the state of the pins to "default" on boot and
runtime resume, and to "sleep" at runtime suspend. This way we
will dynamically save power on the SPI busses, for example some
electronic designs may be able to ground the pins when unused
instead of pull-up. Some pin controllers may want to set the
pins as wake-up sources when sleeping.
Effect on platforms using the PL022 driver:
- If the platform does not use pin control - no semantic effect,
the pinctrl stubs will kick in and resolve the situation.
- Platforms using this driver and have pin control but no
function defined for the PL022 need to either supply a
"default" function in their map or enable pinctrl dummies
so the driver is satisfied.
- Platforms using this driver with hogs for setting up the PL022
pin control - stop using hogs to take the pl022 pin control
handle, let the driver handle this.
I'be looked at some platforms that may be affected:
- SPEAr: appears to define the proper functions in their device
trees and not hogging them, so things should be smooth, the
driver will simply start to take its pins.
- Ux500: the proper function is defined and will be taken properly
by the driver. New sleep states introduced by a separate patch to
ux500 but no regression, since the default state is sufficient.
- U300: old hog deleted as part of this patch.
- LPC32xx: does not appear to be using pinctrl.
- ARM Integrator IMPD1, RealView & Versatile: does not use pinctrl.
