Linus Torvalds bfc7249cc2 Please consider pulling the clk framework changes toward 3.19. It is
much later than usual due to several last minute bugs that had to be
 addressed. As usual the majority of changes are new drivers and
 modifications to existing drivers. The core recieved many fixes along
 with the groundwork for several large changes coming in the future which
 will better parition clock providers from clock consumers.

Hans de Goede a9f8cda32a ARM: dts: sunxi: Update simplefb nodes so that u-boot can find them
Review of the u-boot sunxi simplefb patches has led to the decision that
u-boot should not use a specific path to find the nodes as this goes contrary
to how devicetree usually works.

Instead a platform specific compatible + properties should be used for this.

The simplefb bindings have already been updated to reflect this, this patch
brings the sunxi devicetree files in line with the new binding, and the
actual u-boot implementation as it is going upstream.

Note for now we point directly to the parent rather then to the de_be0 mod-clk

The dma controller requires that the ahb1 bus clock be driven by pll6
for peripheral access to work. Previously this was done in the dma
controller driver, but was since removed as part of a series to unify
the ahb1_mux and ahb1 clock drivers, in

    14e0e28 dmaengine: sun6i: Remove obsolete clk muxing code

Unfortunately the rest of that series did not make it, leaving us with
broken dma on sun6i.

properties in the dma controller node.

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.

Merge tag 'dt-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

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"

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.

Hans de Goede 536a44d427 ARM: sun7i/sun6i: dts: Fix IRQ number for sun6i NMI controller
The IRQ line used in sun6i-a31.dtsi for the NMI controller is wrong.
This causes a IRQ storm since the NMI controller is repeatedly fired.
This patch fixes this problem assigning the correct IRQ number to the
NMI controller.

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.
