Pull ARM SoC fixes from Arnd Bergmann:
"A first set of bug fixes that didn't make it for the merge window, and
two Kconfig cleanups that still make sense at this point.
Unfortunately, one of the two cleanups caused an unintended change in
the original version, so we had to revert one part of it and do some
more testing to ensure the rest is really fine. There was also a
last-minute rebase of the patches to remove another bad commit"

A number of configurations spit out warnings similar to:
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)
Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
eventually get rid of CACHE_PL310, surround these errata options with an
if CACHE_L2X0 conditional rather than repeating the dependency against
each.

The System Type menu is getting quite long with platforms and is
inconsistent in handling of sub-arch specific options. Tidy up the menu
by making platform options a menuconfig entry containing any platform
specific config items.

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.

Commit d941f86fad41b ("ARM: l2c: AM43x: add L2 cache support") enabled
the L2 cache support for the am43xx SoC, but caused a build regression
when the driver for that cache controller is disabled:
arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
:(.init.text+0xb20): undefined reference to `omap_l2_cache_init'
This did not happen for OMAP4, which has the same call, but enables
the l2x0 driver unconditionally. We could do the same thing for
am43xx, but it seems better to allow turning it off and make the
code work in either case.
This adds an inline wrapper for omap_l2_cache_init for the disabled
case, and removes the 'select' from OMAP4 so it becomes a user
visible option.

Pull pwm changes from Thierry Reding:
"The majority of these changes are cleanups and fixes across all
drivers. Redundant error messages are removed and more PWM
controllers set the .can_sleep flag to signal that they can't be used
in atomic context.
Support is added for the Broadcom Kona family of SoCs and the Intel
LPSS driver can now probe PCI devices in addition to ACPI devices.
Upon shutdown, the pwm-backlight driver will now power off the
backlight. It also uses the new descriptor-based GPIO API for more
concise GPIO handling.
A large chunk of these changes also converts platforms to use the
lookup mechanism rather than relying on the global number space to
reference PWM devices. This is largely in preparation for more
unification and cleanups in future patches. Eventually it will allow
the legacy PWM API to be removed"

Duty Cycle Correction(DCC) needs to be enabled if the MPU is to run at
frequencies beyond 1.4GHz for OMAP5, DRA75x, DRA72x.
MPU DPLL has a limitation on the maximum frequency it can be locked
at. Duty Cycle Correction circuit is used to recover a correct duty
cycle for achieving higher frequencies (hardware internally switches
output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)).
For further information, See the note on OMAP5432 Technical Reference
Manual(SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters",
and also the "OMAP543x ES2.0 DM Operating Conditions Addendum v0.5"
chapter 2.1 "Micro Processor Unit (MPU)". Equivalent information is
present in relevant DRA75x, 72x documentation(SPRUHP2E, SPRUHI2P).

Pull ARM updates from Russell King:
- Major clean-up of the L2 cache support code. The existing mess was
becoming rather unmaintainable through all the additions that others
have done over time. This turns it into a much nicer structure, and
implements a few performance improvements as well.
- Clean up some of the CP15 control register tweaks for alignment
support, moving some code and data into alignment.c
- DMA properties for ARM, from Santosh and reviewed by DT people. This
adds DT properties to specify bus translations we can't discover
automatically, and to indicate whether devices are coherent.
- Hibernation support for ARM
- Make ftrace work with read-only text in modules
- add suspend support for PJ4B CPUs
- rework interrupt masking for undefined instruction handling, which
allows us to enable interrupts earlier in the handling of these
exceptions.
- support for big endian page tables
- fix stacktrace support to exclude stacktrace functions from the
trace, and add save_stack_trace_regs() implementation so that kprobes
can record stack traces.
- Add support for the Cortex-A17 CPU.
- Remove last vestiges of ARM710 support.
- Removal of ARM "meminfo" structure, finally converting us solely to
memblock to handle the early memory initialisation.

Pull USB driver updates from Greg KH:

Nothing huge here, but lots of little things in the USB core, and in
lots of drivers. Hopefully the USB power management will be work
better now that it has been reworked to do per-port power control
dynamically. There's also a raft of gadget driver updates and fixes,
CONFIG_USB_DEBUG is finally gone now that everything has been
converted over to the dynamic debug inteface, the last hold-out
drivers were cleaned up and the config option removed. There were
also other minor things all through the drivers/usb/ tree, the
shortlog shows this pretty well.

- SMP rework on Allwinner A31
- Xilinx Zynq support for SOC_BUS, big endian

L2 cache initialization for OMAP4 redundantly sets the cache policy to
Round-Robin. This is not needed since thats the PL310 default anyway.
Removing this reduces the number of platform specific aux control
settings.

Avoid reading directly from the L2 registers in platform code. The L2
code will have already saved the register values itself into the
l2x0_saved_regs structure, so platform code should just move these
values to where they're required.
This is safe because the L2x0 will have been initialised by an early
initcall, whereas the OMAP4 PM code is initialised late.

Since we now always enable NS access to the unlock registers, this can
be removed from OMAP4. Remove the NS access bit for the interrupt
registers from OMAP4 as well - nothing in the kernel accesses that yet,
and we can add it in core code when we have the need.

The cache size should already be present in the L2 cache auxiliary
control register: it is part of the integration process to configure
the hardware IP. Most platforms get this right, yet still many
cargo-cult program, and assume that they always need specifying to
the L2 cache code. Remove them so we can find out which really need
this.

Since we now automatically enable early BRESP in core L2C-310 code when

We have a mixture of different devices with different register layouts,

Move the panel/encoder driver compatible-string converter from
arch/arm/mach-omap2/display.c to omapdss driver. That is a more logical
place for it, as it's really an omapdss internal hack.
The code is rewritten to follow the video node graph, starting from
omapdss. This removes the need to have the device compatible-string
database.

Merge "ARM: omap pm changes for v3.16 merge window, resend" from Tony Lindgren:
PM related fixes for omap3 that were discovered during omap3
conversion to device tree. This series sets up the PMIC signaling
in a way where we can test for PM regressions easily by
looking at state of the the sys_clkreq and sys_off_mode pins.
Note that this series alone does not make omap3 PM to cut
off core voltage during off-idle, changes to twl4030-power.c
configurations are still needed. Those will be posted
separately.

usb: patches for v3.16 merge window
Not a lot here during this merge window. Mostly we just have
the usual miscellaneous patches (removal of unnecessary prints,
proper dependencies being added to Kconfig, build warning fixes,
new device ID, etc.
Other than those, the only important new features are the
new support for OS Strings which should help Linux Gadget
Drivers behave better under MS Windows. Also Babble Recovery
implementation for MUSB on AM335x. Lastly, we also have
ARCH_QCOM PHY support though phy-msm.

In omap2_common_pm_late_init suspend_set_ops was called to set common
suspend handling functions for all omap platforms. This created two
problems. First, these suspend ops were being set for all platforms,
regardless of whether or not suspend support has been integrated so in
the case of AM33XX, suspend to mem was presented as available but
failed every time. Second, some platforms will need to define a
completely separate set of suspend ops, such as AM33XX, due to
differences from previous omap platforms so there is no need to
always set the common omap ops.
This patch moves the suspend_set_ops call from omap2_common_pm_late_init
into a separate function that then gets called in the omap*_pm_init
functions for each platform.

On OMAP4 panda board, there have been several bug reports about boot
hang and lock-ups with CPU_IDLE enabled. The root cause of the issue
is missing interrupts while in idle state. Commit cb7094e8 {cpuidle / omap4 :
use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common
code for right reasons but on OMAP4 which suffers from a nasty ROM code
bug with GIC, commit ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..},
we loose interrupts which leads to issues like lock-up, hangs etc.
Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP
flag} and 54769d6 {cpuidle: OMAP4: remove timer broadcast initialization} to
avoid the issue. With this change, OMAP4 panda boards, the mentioned
issues are getting fixed. We no longer loose interrupts which was the cause
of the regression.
