For device tree based booting, we need to use wake-up
interrupts like we already do for some omaps. This fixes
a PM regression on beagleboard compared to legacy booting.

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.

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>;

For v3.14 and prior, 1-bit Hamming code ECC via software was used
for NAND on this board.
Commit c06c52701695 in v3.15 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.
This ECC layout change causes NAND filesystems created in v3.14
and prior to be unusable in v3.15 and later. So revert back to
using software ECC scheme.

Working on Gigabit/PCIe support in U-Boot for Apalis T30 I realised
that the current device tree source includes for our modules only
happen to work due to referencing the on-carrier 5v0 supply from USB
which is not at all available on-module. The modules actually contain
TPS60150 charge pumps to generate the PMIC required 5 volts from the
one and only 3.3 volt module supply. This patch fixes this.
(Note: When back-porting this to v3.16 stable releases, simply drop the
change to tegra30-apalis.dtsi; that file was added in v3.17)

- ARM: sh7372, sh73a0

Increase max i2c bus frequency beyond the default for faster
data transfers. According to the manual, these faster speeds are
only available when the board is wired up the right way. In this case,
the vendor kernel has run at this speed for a long time.
sda-delay is needed for talking to RTC on PMIC, otherwise the i2c
controller never sees an ACK. Strangely the other PMIC i2c slave (the
main one) works fine even without this delay. I Chose value 100 to
match the vendor kernel.

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.

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.

This patch fixes booting when idmap pgd lays above 4gb. Commit
4756dcbfd37 mostly had fixed this, but it'd failed to load upper bits.
Also this fixes adding TTBR1_OFFSET to TTRR1: if lower part overflows
carry flag must be added to the upper part.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO update from Linus Walleij:
"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"

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.
