Commit 0b46b8a718c6 (clocksource: arch_timer: Fix code to use physical
timers when requested) introduces the use of physical counters in the
ARM architected timer driver. However, he arm64 kernel uses CNTVCT in
VDSO. When booting in EL2, the kernel switches to the physical timers to
make things easier for KVM but it continues to use the virtual counter
both in user and kernel. While in such scenario CNTVCT == CNTPCT (since
CNTVOFF is initialised by the kernel to 0), we want to spot firmware
bugs corrupting CNTVOFF early (which would affect CNTVCT).

The Exynos IOMMU driver uses the ARM specific dmac_flush_range() and
outer_flush_range() functions. This breaks the build on arm64 allmodconfig
in -next since support has been merged for some Exynos ARMv8 SoCs. Add a
dependency on ARM to keep things building until either the driver has the
ARM dependencies removed or the ARMv8 architecture code implements these
ARM specific APIs.

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.

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.

support. The branch is the largest one and contains 513 out of the
total 972 non-merge arm-soc changesets for 3.19.

are fairly complete. As usual, these get extended over time.

and for some reason could not get merged through the respective
subsystem maintainer tree.
The largest single change here this time around is the Tegra
iommu/memory controller driver, which gets updated to the new
iommu DT binding. More drivers like this are likely to follow
for the following merge window, but we should be able to do
those through the iommu maintainer.
Other notable changes are:
* reset controller drivers from the reset maintainer (socfpga, sti, berlin)
* fixes for the keystone navigator driver merged last time
* at91 rtc driver changes related to the at91 cleanups
* ARM perf driver changes from Will Deacon

...
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.

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 is split out from the other cleanups purely based on the size
of the branch.

performance requirements that were requested by the Gluster
distributed filesystem. Specifically, dm-thinp now takes care to
aggregate IO that will be issued to the same thinp block before
issuing IO to the underlying devices. This really helps improve
performance on HW RAID6 devices that have a writeback cache because it
avoids RMW in the HW RAID controller.
- Some stable fixes: fix leak in DM bufio if integrity profiles were
enabled, use memzero_explicit in DM crypt to avoid any potential for
information leak, and a DM cache fix to properly mark a cache block
dirty if it was promoted to the cache via the overwrite optimization.
- A few simple DM persistent data library fixes
- DM cache multiqueue policy block promotion improvements.
- DM cache discard improvements that take advantage of range
(multiblock) discard support in the DM bio-prison. This allows for
much more efficient bulk discard processing (e.g. when mkfs.xfs
discards the entire device).
- Some small optimizations in DM core and RCU deference cleanups
- DM core changes to suspend/resume code to introduce the new internal
suspend/resume interface that the DM thin-pool target now uses to
suspend/resume active thin devices when the thin-pool must
suspend/resume. This avoids forcing userspace to track all active
thin volumes in a thin-pool when the thin-pool is suspended for the
purposes of metadata or data space resize.

suspend/resume active thin devices when the thin-pool must
suspend/resume.
This avoids forcing userspace to track all active thin volumes in a
thin-pool when the thin-pool is suspended for the purposes of
metadata or data space resize.

The main thing this time around is support for suspend mode
configuration from DT which will enable some very useful power savings
on systems where we can't rely on the bootloader configuration. We
still don't really support dynamic configuration of this at runtime,
that may come later if there is any demand.
- Support for specifying the target regulation mode and voltage during
system suspend via DT, enabling power savings in that mode.
- Reduce the default verbosity of the logging on boot, improving boot
times especially for systems with very large numbers of regulators.
- Lots of cleanups and fixes for Maxim PMIC drivers.
- New driver for Richtek RT5033.

Instead of having a local function taking care of sending the tuning
command, let's use the common mmc_send_tuning() API provided by the mmc
core. In this way the request will be handled as any other request by
sdhci core.
As an effect of this change, the pm_runtime_get_sync() call at
esdhc_prepare_tuning() isn't needed any more.
This patch will also introduce another change in behavior, since before
the response pattern to the tuning command wasn't verified by
sdhci-esdhc-imx. The mmc_send_tuning() does that.

* clocksource/physical-timers:
clocksource: arch_timer: Allow the device tree to specify uninitialized timer registers
clocksource: arch_timer: Fix code to use physical timers when requested
Some 32-bit (ARMv7) systems 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 (CNTVOFF)
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)
On systems like the above, it doesn't make sense to use the virtual
counter. 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.
This adds an optional property which can inform the kernel of this
situation, and firmware is free to remove the property if it is going
to initialize the CNTVOFF registers when each CPU comes out of reset.
Currently, the best course of action in this case is to use the
physical timer, which is why it is important that CNTHCTL hasn't been
changed from its reset value and it's a reasonable assumption given
that the firmware has never entered HYP mode.
Note that it's been said that on ARMv8 systems the firmware and
kernel really can't be architected as described above. That means
using the physical timer like this really only makes sense for ARMv7
systems.

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.
