Linus Torvalds f83ccb9358 ARM: SoC: device tree changes
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.

Linus Torvalds 683b6c6f82 Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq code updates from Thomas Gleixner:
 "The irq department proudly presents:

   - Another tree wide sweep of irq infrastructure abuse.  Clear winner
     of the trainwreck engineering contest was:
         #include "../../../kernel/irq/settings.h"

   - Tree wide update of irq_set_affinity() callbacks which miss a cpu
     online check when picking a single cpu out of the affinity mask.

   - Tree wide consolidation of interrupt statistics.

   - Updates to the threaded interrupt infrastructure to allow explicit
     wakeup of the interrupt thread and a variant of synchronize_irq()
     which synchronizes only the hard interrupt handler.  Both are
     needed to replace the homebrewn thread handling in the mmc/sdhci
     code.

   - New irq chip callbacks to allow proper support for GPIO based irqs.
     The GPIO based interrupts need to request/release GPIO resources
     from request/free_irq.

   - A few new ARM interrupt chips.  No revolutionary new hardware, just
     differently wreckaged variations of the scheme.

   - Small improvments, cleanups and updates all over the place"

I was hoping that that trainwreck engineering contest was a April Fools'
joke.  But no.

Linus Torvalds 9b6d351a75 ARM: SoC DT updates for 3.14
DT and DT-conversion-related changes for various ARM platforms. Most
 of these are to enable various devices on various boards, etc, and not
 necessarily worth enumerating.
 
 New boards and systems continue to come in as new devicetree files that
 don't require corresponding C changes any more, which is indicating that
 the system is starting to work fairly well.
 
 A few things worth pointing out:
 
 * ST Ericsson ux500 platforms have made the major push to move over to fully
   support the platform with DT.
 * Renesas platforms continue their conversion over from legacy platform devices
   to DT-based for hardware description.

Maxime Ripard 6f97dc8d46 ARM: sun6i: dt: Fix interrupt trigger types
The Allwinner A31 uses the ARM GIC as its internal interrupts controller. The
GIC can work on several interrupt triggers, and the A31 was actually setting it
up to use a rising edge as a trigger, while it was actually a level high
trigger, leading to some interrupts that would be completely ignored if the
edge was missed.

Maxime Ripard 24a661e994 ARM: sun6i: Add the reset controller to the DTSI
The A31 has a reset controller IP that maintains a few other IPs in
reset, among which we can find the UARTs, high speed timers or the I2C.
Now that we have support for them, add the reset controllers to the DTSI.

Maxime Ripard 140e1721d1 ARM: sunxi: dt: Add PIO controller to A31 DTSI
The A31 has a different set of pins than the one found on the A10 and
A13. Now that we have support for the A31 pin set in the pinctrl driver,
we can enable it in the DTSI with its own compatible.
