Maxime Ripard 8358aada4e ARM: sunxi: dt: Fix whitespace errors
A few lines (probably copy pasted) have an indentation mixing tabs and

Fix those, and while we're at it, fix the space-indented sections.

Maxime Ripard c0c2eb2476 ARM: sunxi: dt: Remove the FSF address
The FSF address triggers a warning on checkpatch, saying that the FSF
license is already present in the Linux source code, and that it has
already changed in the past.

Remove it from our DT, as suggested.

Chen-Yu Tsai f22fe1c5ab ARM: dts: sun6i: Set PLL6 as parent to AHB1 clock in AHB1 clock node
On sun6i we already have PLL6 as AHB1 clock's parent. However this was
previously set in the dma controller node, which takes effect when the
dma controller is probed.

We want this to take effect as soon as possible, so hrtimer rate
calculation is correct, and to be sure the AHB1 clock rate remains as
stable as possible.

Chen-Yu Tsai 3a2bc642ab ARM: dts: sun6i: Add cpu clock reference and operating points to dtsi
The cpu core is clocked from the "cpu" clock. Add a reference to it
in the first cpu node. Also add "cpu0" label to the node.

The operating points were taken from the a list compiled by Maxime Ripard,
which is based on A31 FEX files from the sunxi-boards repository. Not all
boards have the same settings. The settings in this patch are the ones
shared by A/B/C revisions, plus the default clock setting from u-boot.

Hans de Goede 4c1bb9c318 ARM: dts: sunxi: Add address- and size-cells properties to the mmc ctrl nodes
Sometimes we need to specify non-probably information for sdio devices in the
devicetree, this is done through child nodes addressed by the reg property,
whereby the reg property refers to the sdio function number, see;
Documentation/devicetree/bindings/mmc/mmc.txt

This commit adds the necessary address- and size-cells properties to the mmc
controller nodes in the dtsi files, so that dts files needing such a child
node do not need to specify these themselves.

Linus Torvalds 18a8d49973 The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly the framework core underwent a bit of surgery with
 two major changes. The boundary between the clock core and clock
 providers (e.g clock drivers) is now more well defined with dedicated
 provider helper functions. struct clk no longer maps 1:1 with the
 hardware clock but is a true per-user cookie which helps us tracker
 users of hardware clocks and debug bad behavior. The second major change
 is the addition of rate constraints for clocks. Rate ranges are now
 supported which are analogous to the voltage ranges in the regulator
 framework. Unfortunately these changes to the core created some
 breakeage. We think we fixed it all up but for this reason there are
 lots of last minute commits trying to undo the damage.

Linus Torvalds a233bb742a ARM: SoC DT updates
DT changes continue to be the bulk of our merge window contents.
 
 We continue to have a large set of changes across the board as new platforms
 and drivers are added.
 
 Some of the new platforms are:
 - Alphascale ASM9260
 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS
 contents from GPL to GPLv2+/X11 so that the same files can be reused in
 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down
 the road.

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.

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.

 "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"

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.

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.
