The GIC controller doesn't provides any facility to configure the wakeup sources. For the same reason, GIC chip implementation can't provide irq_set_wake functionality, but that results in the irqchip core preventing the systems from entering sleep states like "suspend to RAM". The GICv1/v2 controllers support wakeup events. They signal these wakeup events even when CPU interface is disabled which means the wakeup outputs are always enabled with the required logic in always-on domain. An implementation can powerdown the GIC completely, but then the wake-up must be relayed to some control logic within the power controller that acts as wake-up interrupt controller. Setting the IRQCHIP_SKIP_SET_WAKE flags will ensure that the interrupts from GIC can work as wakeup interrupts and resume from suspend-to-{idle, ram}. The wakeup interrupt sources need to use enable_irq_wake() and the irqchip core will then set the IRQD_WAKEUP_STATE flag. Also it's always safer to mask all the non wakeup interrupts are masked at the chip level when suspending. The irqchip infrastructure can handle masking of those interrupts at the chip level. The chip implementation just have to indicate that with IRQCHIP_MASK_ON_SUSPEND. This patch enables IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so that the irqchip core allows and handles the power managemant wake up modes.

Reorganize struct msi_desc so it could be reused by other MSI drivers. We have the following layout now: struct msi_desc { /* Shared device/bus independent data */ ... union { /* PCI specific data */ struct { ... }; }; }; We need to have anonymous union and a anonymous structure for the PCI fields, otherwise we would have to change all instances using these fields. For non PCI devices we will enforce a proper namespace and a non anonymous structure.

As it turns out the current IRQ number will *always* be available from SIR register which renders the reads of PENDING registers as plain unnecessary overhead. In order to catch any situation where SIR reads as zero, we're adding a WARN() to turn it into a very verbose error and users actually report it. With this patch average running time of omap_intc_handle_irq() reduced from about 28.5us to 19.8us as measured by the kernel function profiler. Tested with BeagleBoneBlack Rev A5C.
