Merge tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull arm-soc: soc specific changes (part 2) from Olof Johansson:
 "This adds support for the spear13xx platform, which has first been
  under review a long time ago and finally been completed after generic
  spear work has gone into the clock, dt and pinctrl branches.

  Also a number of updates for the samsung socs are part of this branch."

Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much
worse than they are: the exonys5 init code was refactored in commit
fd454997 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and
then commit f10590c9 ("ARM: EXYNOS: add GPC4 bank instance") added a
new gpio chip define and did tiny updates to the init code.

So the conflict diff looks like hell, but it's actually a fairly simple
change.

* Samsung Exynos Interrupt Combiner Controller



Samsung's Exynos4 architecture includes a interrupt combiner controller which

can combine interrupt sources as a group and provide a single interrupt request

for the group. The interrupt request from each group are connected to a parent

interrupt controller, such as GIC in case of Exynos4210.



The interrupt combiner controller consists of multiple combiners. Upto eight

interrupt sources can be connected to a combiner. The combiner outputs one

combined interrupt for its eight interrupt sources. The combined interrupt

is usually connected to a parent interrupt controller.



A single node in the device tree is used to describe the interrupt combiner

controller module (which includes multiple combiners). A combiner in the

interrupt controller module shares config/control registers with other

combiners. For example, a 32-bit interrupt enable/disable config register

can accommodate upto 4 interrupt combiners (with each combiner supporting

upto 8 interrupt sources).



Required properties:

- compatible: should be "samsung,exynos4210-combiner".

- interrupt-controller: Identifies the node as an interrupt controller.

- #interrupt-cells: should be <2>. The meaning of the cells are

	* First Cell: Combiner Group Number.

	* Second Cell: Interrupt number within the group.

- reg: Base address and size of interrupt combiner registers.

- interrupts: The list of interrupts generated by the combiners which are then

    connected to a parent interrupt controller. The format of the interrupt

    specifier depends in the interrupt parent controller.



Optional properties:

- samsung,combiner-nr: The number of interrupt combiners supported. If this

  property is not specified, the default number of combiners is assumed

  to be 16.

- interrupt-parent: pHandle of the parent interrupt controller, if not

  inherited from the parent node.





Example:



	The following is a an example from the Exynos4210 SoC dtsi file.



	combiner:interrupt-controller@10440000 {

		compatible = "samsung,exynos4210-combiner";

		interrupt-controller;

		#interrupt-cells = <2>;

		reg = <0x10440000 0x1000>;

		interrupts = <0 0 0>, <0 1 0>, <0 2 0>, <0 3 0>,

			     <0 4 0>, <0 5 0>, <0 6 0>, <0 7 0>,

			     <0 8 0>, <0 9 0>, <0 10 0>, <0 11 0>,

			     <0 12 0>, <0 13 0>, <0 14 0>, <0 15 0>;
