Pull ARM SoC device tree changes from Arnd Bergmann:
"A large part of the arm-soc patches are nowadays DT changes, adding
support for new SoCs, boards and devices without changing kernel
source. The plan is still to move the devicetree files out of the
kernel tree and reduce the amount of churn going on here, but we keep
finding reasons to delay doing that.Changes are really all over the place, with little sticking out
particularly. We have contributions from a total of 116 people in
this branch.Unfortunately, the size of this branch also causes a significant
number of conflicts at the moment, typically when subsystem
maintainers merge patches that change the driver at the same time as
the dts files. In most cases this could be avoided because the dts
changes are supposed to be compatible in both ways, and we are asking
everyone to send ARM dts changes through our tree only"* tag 'dt-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (541 commits)

On PXT and COMe-cPC2 boards it is observed that the hardware
mutex is acquired but not being released during initialization.
This can result in a hang-up during boot if the driver is built
into the kernel.Releasing the mutex twice if it was acquired fixes the problem.
Subsequent request/release cycles work as expected, so the fix is
only needed during initialization.Cc:

The tps65910_i2c_probe() allocates regmap_irq_chip in

Signed-off-by: Lee Jones -
Fixes: 4aab3fadad32 ("mfd: tps65910: Move interrupt implementation code to mfd file")
tps65910_irq_init() sets 'tps65910->chip_irq' before calling
regmap_add_irq_chip(). If the regmap_add_irq_chip() call fails in
memory allocation of regmap_irq_chip_data members then:1. The 'tps65910->chip_irq' will still hold some value
2. 'tps65910->irq_data' will be pointing to already freed memory
(because regmap_add_irq_chip() will free it on error)This results in invalid memory access during driver remove because the
tps65910_irq_exit() tests whether 'tps65910->chip_irq' is not zero.Cc:

Signed-off-by: Lee Jones -
Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different
register layouts for the iTCO than the current v1 and v2 iTCO.
Differences from previous iTCO versions include:
- The ACPI space is enabled in the "ACPI base address" register instead
of the "ACPI control register"- The "no reboot" functionality is set in the "Power Management
Configuration" register instead of the "General Control and Status"
(GCS) register or PCI configuration space.- The "ACPI Control Register" is not present on v3. The "Power
Management Configuration Base Address" register resides at the same
address is Avoton/Bay Trail.To differentiate these newer chipsets create a new v3 iTCO version and
update the MFD driver to support them.Signed-off-by: Peter Tyser
