8fd46439e1 ARM: dts: omap54xx-clocks: Fix the l3 and l4 clock rates
Similarly to DRA7, OMAP5 has l3 and l4 clock rates incorrectly calculated.
Fixed by using proper divider clock types for the clock nodes.

cc824534d4 ARM: OMAP2+: hwmod: Rearm wake-up interrupts for DT when MUSB is idled
Looks like MUSB cable removal can cause wake-up interrupts to
stop working for device tree based booting at least for UART3
even as nothing is dynamically remuxed. This can be fixed by
calling reconfigure_io_chain() for device tree based booting
in hwmod code. Note that we already do that for legacy booting
if the legacy mux is configured.

My guess is that this is related to UART3 and MUSB ULPI
hsusb0_data0 and hsusb0_data1 support for Carkit mode that
somehow affect the configured IO chain for UART3 and require
rearming the wake-up interrupts.

In general, for device tree based booting, pinctrl-single
calls the rearm hook that in turn calls reconfigure_io_chain
so calling reconfigure_io_chain should not be needed from the
hwmod code for other events.

So let's limit the hwmod rearming of iochain only to
HWMOD_FORCE_MSTANDBY where MUSB is currently the only user
of it. If we see other devices needing similar changes we can
add more checks for it.

9a02ae4ed4 ARM: OMAP2+: omap_device: remove warning that clk alias already exists
When an alias for a clock already exists the warning is printed. For
every module with a main_clk defined, a clk alias for fck is added.
There are some components that have the same main_clk defined, so this
is a really normal situation.

For example the am33xx edma device has 4 components using the same main
clock. So there are three warnings in the boot log for this already
existing clock alias:
	platform 49000000.edma: alias fck already exists
	platform 49000000.edma: alias fck already exists
	platform 49000000.edma: alias fck already exists

As this is only interesting for developers, this patch changes the
message to a debug message.

e49d519c45 ARM: dts: DRA7: fix interrupt-cells for GPIO
GPIO modules are also interrupt sources. However, they require both the
GPIO number and IRQ type to function properly.

By declaring that GPIO uses interrupt-cells=<1>, we essentially do not
allow users of the nodes to use the interrupt property appropritely.

With this change, the following now works:

interrupt-parent = <&gpio6>;
interrupts = <5 IRQ_TYPE_LEVEL_LOW>;

59d05b5183 ARM: imx: fix TLB missing of IOMUXC base address during suspend
After the suspend routine running in OCRAM puts DDR into self-refresh,
it will access IOMUXC block to float DDR IO for power saving.  A TLB
missing of IOMUXC base address may happen in this case, and triggers an
access to DDR, and thus hangs the system.

The failure is discovered by running suspend/resume on a Cubox-i board.
Though the issue is not Cubox-i specific, it can be hit the on the board
quite easily with the 3.15 or 3.16 kernel.

Fix the issue with a dummy access to IOMUXC block at the beginning of
suspend routine, so that the address translation can be filled into TLB
before DDR is put into self-refresh.

ae36e95cf8 The branch contains the following device tree changes the v3.17 merge
window:
 
 Group changes to the device tree. In preparation for adding device tree
 overlay support, OF_DYNAMIC is reworked so that a set of device tree
 changes can be prepared and applied to the tree all at once. OF_RECONFIG
 notifiers see the most significant change here so that users always get
 a consistent view of the tree. Notifiers generation is moved from before
 a change to after it, and notifiers for a group of changes are emitted
 after the entire block of changes have been applied
 
 Automatic console selection from DT. Console drivers can now use
 of_console_check() to see if the device node is specified as a console
 device. If so then it gets added as a preferred console. UART devices
 get this support automatically when uart_add_one_port() is called.
 
 DT unit tests no longer depend on pre-loaded data in the device tree.
 Data is loaded dynamically at the start of unit tests, and then unloaded
 again when the tests have completed.
 
 Also contains a few bugfixes for reserved regions and early memory setup.

Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux

Pull device tree updates from Grant Likely:
 "The branch contains the following device tree changes the v3.17 merge
  window:

  Group changes to the device tree.  In preparation for adding device
  tree overlay support, OF_DYNAMIC is reworked so that a set of device
  tree changes can be prepared and applied to the tree all at once.
  OF_RECONFIG notifiers see the most significant change here so that
  users always get a consistent view of the tree.  Notifiers generation
  is moved from before a change to after it, and notifiers for a group
  of changes are emitted after the entire block of changes have been
  applied

  Automatic console selection from DT.  Console drivers can now use
  of_console_check() to see if the device node is specified as a console
  device.  If so then it gets added as a preferred console.  UART
  devices get this support automatically when uart_add_one_port() is
  called.

  DT unit tests no longer depend on pre-loaded data in the device tree.
  Data is loaded dynamically at the start of unit tests, and then
  unloaded again when the tests have completed.

  Also contains a few bugfixes for reserved regions and early memory
  setup"

The DTS addition should never have been merged through the DRM tree in
the first place, and it lacked an ack from the platform maintainer
(who would have known that the disp_pd reference got removed).

01601b3495 ARM: EXYNOS: Fix suspend/resume sequences
Due to recent consolidation of Exynos suspend and cpuidle code, some
parts of suspend and resume sequences are executed two times, once from
exynos_pm_syscore_ops and then from exynos_cpu_pm_notifier() and thus it
breaks suspend, at least on Exynos4-based boards. In addition, simple
core power down from a cpuidle driver could, in case of CPU 0 could
result in calling functions that are specific to suspend and deeper idle
states.

This patch fixes the issue by moving those operations outside the CPU PM
notifier into suspend and AFTR code paths. This leads to a bit of code
duplication, but allows additional code simplification, so in the end
more code is removed than added.

06b49ea43c This is the bulk of GPIO changes for the v3.17 development
cycle, and this time we got a lot of action going on and
 it will continue:
 
 - The core GPIO library implementation has been split up in
   three different files:
   - gpiolib.c for the latest and greatest and shiny GPIO
     library code using GPIO descriptors only
   - gpiolib-legacy.c for the old integer number space API
     that we are phasing out gradually
   - gpiolib-sysfs.c for the sysfs interface that we are
     not entirely happy with, but has to live on for
     ABI compatibility
 
 - Add a flags argument to *gpiod_get* functions, with some
   backward-compatibility macros to ease transitions. We
   should have had the flags there from the beginning it
   seems, now we need to clean up the mess. There is a plan
   on how to move forward here devised by Alexandre Courbot
   and Mark Brown.
 
 - Split off a special <linux/gpio/machine.h> header for the
   board gpio table registration, as per example from the
   regulator subsystem.
 
 - Start to kill off the return value from gpiochip_remove()
   by removing the __must_check attribute and removing all
   checks inside the drivers/gpio directory. The rationale
   is: well what were we supposed to do if there is an error
   code? Not much: print an error message. And gpiolib already
   does that. So make this function return void eventually.
 
 - Some cleanups of hairy gpiolib code, make some functions
   not to be used outside the library private and make sure
   they are not exported, remove gpiod_lock/unlock_as_irq()
   as the existing function is for driver-internal use and
   fine as it is, delete gpio_ensure_requested() as it is
   not meaningful anymore.
 
 - Support the GPIOF_ACTIVE_LOW flag from gpio_request_one()
   function calls, which is logical since this is already
   supported when referencing GPIOs from e.g. device trees.
 
 - Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use
   the gpiolib irqchip helpers cutting down on GPIO irqchip
   boilerplate a bit more.
 
 - New driver for the Zynq GPIO block.
 
 - The usual incremental improvements around a bunch of
   drivers.
 
 - Janitorial syntactic and semantic cleanups by Jingoo Han,
   and Rickard Strandqvist especially.

12db5562e0 kexec: load and relocate purgatory at kernel load time
Load purgatory code in RAM and relocate it based on the location.
Relocation code has been inspired by module relocation code and purgatory
relocation code in kexec-tools.

Also compute the checksums of loaded kexec segments and store them in
purgatory.

Arch independent code provides this functionality so that arch dependent
bootloaders can make use of it.

Helper functions are provided to get/set symbol values in purgatory which
are used by bootloaders later to set things like stack and entry point of
second kernel etc.

308c09f17d lib/scatterlist: make ARCH_HAS_SG_CHAIN an actual Kconfig
Rather than have architectures #define ARCH_HAS_SG_CHAIN in an
architecture specific scatterlist.h, make it a proper Kconfig option and
use that instead.  At same time, remove the header files are are now
mostly useless and just include asm-generic/scatterlist.h.
