irqchip: add basic infrastructure With the recent creation of the drivers/irqchip/ directory, it is desirable to move irq controller drivers here. At the moment, the only driver here is irq-bcm2835, the driver for the irq controller found in the ARM BCM2835 SoC, present in Rasberry Pi systems. This irq controller driver was exporting its initialization function and its irq handling function through a header file in <linux/irqchip/bcm2835.h>. When proposing to also move another irq controller driver in drivers/irqchip, Rob Herring raised the very valid point that moving things to drivers/irqchip was good in order to remove more stuff from arch/arm, but if it means adding gazillions of headers files in include/linux/irqchip/, it would not be very nice. So, upon the suggestion of Rob Herring and Arnd Bergmann, this commit introduces a small infrastructure that defines a central irqchip_init() function in drivers/irqchip/irqchip.c, which is meant to be called as the ->init_irq() callback of ARM platforms. This function calls of_irq_init() with an array of match strings and init functions generated from a special linker section. Note that the irq controller driver initialization function is responsible for setting the global handle_arch_irq() variable, so that ARM platforms no longer have to define the ->handle_irq field in their DT_MACHINE structure. A global header, <linux/irqchip.h> is also added to expose the single irqchip_init() function to the reset of the kernel. A further commit moves the BCM2835 irq controller driver to this new small infrastructure, therefore removing the include/linux/irqchip/ directory.

ARM: exynos: move exynos4210-combiner to drivers/irqchip Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init for GIC init). This commit split the irqchip initialization into 2 calls to of_irq_init. This does not work because of_irq_init requires interrupt parents to be in the match list. Rather than reverting exynos changes, make it do the proper thing by using IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.

irqchip: hip04: Enable Hisilicon HiP04 interrupt controller HiP04 GIC is the variate of ARM GICv2. ARM GICv2 supports 8 cores. HiP04 GIC extends to support 16 cores. It results that bit fields in GIC_DIST_TARGET & GIC_DIST_SOFTINT are different from ARM GICv2. And the maximium IRQ is downgrade from 1020 to 510. Since different register offset & bitfields definitation breaks compartible with ARM GICv2, create a new hip04 irq driver. And this driver is derived from irq-gic.c to support the Hisilicon HiP04 interrupt controller, which is similar to the GIC, but deviates at some points. Support for power management, non-banked registers, cascaded GICs (and multiple controllers in general) and bigLittle support has been removed from the GIC driver. Affinity related functions have been adjusted to match the Hisilicon hardware implementation.

irqchip: move IRQ driver for Armada 370/XP When the Marvell Armada 370/XP support was included in the kernel, the drivers/irqchip/ directory didn't exist and the minimal infrastructure in it also didn't exist. Now that we have those things in place, we move the Armada 370/XP IRQ controller driver from arch/arm/mach-mvebu/irq-armada-370-xp.c to drivers/irqchip/irq-armada-370-xp.c. Note in order to reduce code movement and therefore ease the review of this patch, we intentionally introduce a forward declaration of armada_370_xp_handle_irq(). It is in fact not needed because this handler can now simply be implemented before armada_370_xp_mpic_of_init(). That will be done in the next commit.

irqchip: sunxi: Rename sunxi to sun4i During the introduction of the Allwinner SoC platforms, sunxi was initially meant as a generic name for all the variants of the Allwinner SoC. It was ok at the time of the support of only the A10 and A13 that looks pretty much the same, but it's beginning to be troublesome with the future addition of the Allwinner A31 (sun6i) that is quite different, and would introduce some weird logic, where sunxi would actually mean in some case sun4i and sun5i but without sun6i... Moreover, it makes the compatible strings naming scheme not consistent with other architectures, where usually for this kind of compability, we just use the oldest SoC name that has this IP, so let's do just this.

irqchip: Renesas INTC External IRQ pin driver This patch adds a driver for external IRQ pins connected to the INTC block on recent SoCs from Renesas. The INTC hardware block usually contains a rather wide range of features ranging from external IRQ pin handling to legacy interrupt controller support. On older SoCs the INTC is used as a general purpose interrupt controller both for external IRQ pins and on-chip devices. On more recent ARM based SoCs with Cortex-A9 the main interrupt controller is the GIC, but IRQ trigger setup still need to happen in the INTC hardware block. This driver implements the glue code needed to configure IRQ trigger and also handle mask/unmask and demux of external IRQ pins hooked up from the INTC to the GIC. Tested on sh73a0 and r8a7779. The hardware varies quite a bit with SoC model, for instance register width and bitfield widths vary wildly. The driver requires one GIC SPI per external IRQ pin to operate. Each driver instance will handle up to 8 external IRQ pins. The SoCs using this driver are currently mainly used together with regular platform devices so this driver allows configuration via platform data to support things like static interrupt base address. DT support will be added incrementally in the not so distant future.

This driver implements the glue code needed to configure IRQ trigger and also handle mask/unmask and demux of external IRQ pins hooked up from the IRQC to the GIC. Tested on r8a73a4 but is designed to work with a wide range of SoCs. The driver requires one GIC SPI per external IRQ pin to operate. Each driver instance will handle up to 32 external IRQ pins. The SoCs using this driver are currently mainly used together with regular platform devices so this driver allows configuration via platform data to support things like static interrupt base address. DT support will be added incrementally in the not so distant future.

DRIVERS: IRQCHIP: CROSSBAR: Add support for Crossbar IP Some socs have a large number of interrupts requests to service the needs of its many peripherals and subsystems. All of the interrupt lines from the subsystems are not needed at the same time, so they have to be muxed to the irq-controller appropriately. In such places a interrupt controllers are preceded by an CROSSBAR that provides flexibility in muxing the device requests to the controller inputs. This driver takes care a allocating a free irq and then configuring the crossbar IP as a part of the mpu's irqchip callbacks. crossbar_init should be called right before the irqchip_init, so that it is setup to handle the irqchip callbacks.

irqchip: vf610-mscm-ir: Add support for Vybrid MSCM interrupt router This adds support for Vybrid's interrupt router. On VF6xx models, almost all peripherals can be used by either of the two CPU's, the Cortex-A5 or the Cortex-M4. The interrupt router routes the peripheral interrupts to the configured CPU. This IRQ chip driver configures the interrupt router to route the requested interrupt to the CPU the kernel is running on. The driver makes use of the irqdomain hierarchy support. The parent is given by the device tree. This should be one of the two possible parents either ARM GIC or the ARM NVIC interrupt controller. The latter is currently not yet supported. Note that there is no resource control mechnism implemented to avoid concurrent access of the same peripheral. The user needs to make sure to use device trees which assign the peripherals orthogonally. However, this driver warns the user in case the interrupt is already configured for the other CPU. This provides a poor man's resource controller.

IRQCHIP: Add new driver for BCM7038-style level 1 interrupt controllers This is the main peripheral IRQ controller on the BCM7xxx MIPS chips; it has the following characteristics: - 64 to 160+ level IRQs - Atomic set/clear registers - Reasonably predictable register layout (N status words, then N mask status words, then N mask set words, then N mask clear words) - SMP affinity supported on most systems - Typically connected to MIPS IRQ 2,3,2,3 on CPUs 0,1,2,3 This driver registers one IRQ domain and one IRQ chip to cover all instances of the block. Up to 4 instances of the block may appear, as it supports 4-way IRQ affinity on BCM7435. The same block exists on the ARM BCM7xxx chips, but typically the ARM GIC is used instead. So this driver is primarily intended for MIPS STB chips.
