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 fd454997d687 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and then commit f10590c9836c ("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. * tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (34 commits) ARM: exynos: fix building with CONFIG_OF disabled ARM: EXYNOS: Add AUXDATA for i2c controllers ARM: dts: Update device tree source files for EXYNOS5250 ARM: EXYNOS: Add device tree support for interrupt combiner ARM: EXYNOS: Add irq_domain support for interrupt combiner ARM: EXYNOS: Remove a new bus_type instance for EXYNOS5 ARM: EXYNOS: update irqs for EXYNOS5250 SoC ARM: EXYNOS: Add pre-divider and fout mux clocks for bpll and mpll ARM: EXYNOS: add GPC4 bank instance ARM: EXYNOS: Redefine IRQ_MCT_L0,1 definition ARM: EXYNOS: Modify the GIC physical address for static io-mapping ARM: EXYNOS: Add watchdog timer clock instance pinctrl: SPEAr1310: Fix pin numbers for clcd_high_res SPEAr: Update MAINTAINERS and Documentation SPEAr13xx: Add defconfig SPEAr13xx: Add compilation support SPEAr13xx: Add dts and dtsi files pinctrl: Add SPEAr13xx pinctrl drivers pinctrl: SPEAr: Create macro for declaring GPIO PINS SPEAr13xx: Add common clock framework support ...

1* Samsung Exynos Interrupt Combiner Controller
2
3Samsung's Exynos4 architecture includes a interrupt combiner controller which
4can combine interrupt sources as a group and provide a single interrupt request
5for the group. The interrupt request from each group are connected to a parent
6interrupt controller, such as GIC in case of Exynos4210.
7
8The interrupt combiner controller consists of multiple combiners. Upto eight
9interrupt sources can be connected to a combiner. The combiner outputs one
10combined interrupt for its eight interrupt sources. The combined interrupt
11is usually connected to a parent interrupt controller.
12
13A single node in the device tree is used to describe the interrupt combiner
14controller module (which includes multiple combiners). A combiner in the
15interrupt controller module shares config/control registers with other
16combiners. For example, a 32-bit interrupt enable/disable config register
17can accommodate upto 4 interrupt combiners (with each combiner supporting
18upto 8 interrupt sources).
19
20Required properties:
21- compatible: should be "samsung,exynos4210-combiner".
22- interrupt-controller: Identifies the node as an interrupt controller.
23- #interrupt-cells: should be <2>. The meaning of the cells are
24 * First Cell: Combiner Group Number.
25 * Second Cell: Interrupt number within the group.
26- reg: Base address and size of interrupt combiner registers.
27- interrupts: The list of interrupts generated by the combiners which are then
28 connected to a parent interrupt controller. The format of the interrupt
29 specifier depends in the interrupt parent controller.
30
31Optional properties:
32- samsung,combiner-nr: The number of interrupt combiners supported. If this
33 property is not specified, the default number of combiners is assumed
34 to be 16.
35- interrupt-parent: pHandle of the parent interrupt controller, if not
36 inherited from the parent node.
37

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

43 combiner:interrupt-controller@10440000 {
44 compatible = "samsung,exynos4210-combiner";
45 interrupt-controller;
46 #interrupt-cells = <2>;
47 reg = <0x10440000 0x1000>;

49 <0 4 0>, <0 5 0>, <0 6 0>, <0 7 0>,
