Merge tag 'irqchip-core-4.1-2' of git://git.infradead.org/users/jcooper/linux into irq/core
irqchip core changes for v4.1 (round 2) from Jason Cooper - gic - Tolerate uni-processor systems better in gic_get_cpumask() - mvebu - Handle per-cpu interrupts properly - Enable PMU interrupts - Enable wakeup source - vybrid - Add MSCM interrupt router - renesas - Add PM and wakeup support

+Freescale Vybrid Miscellaneous System Control - Interrupt Router
+
+The MSCM IP contains multiple sub modules, this binding describes the second
+block of registers which control the interrupt router. The interrupt router
+allows to configure the recipient of each peripheral interrupt. Furthermore
+it controls the directed processor interrupts. The module is available in all
+Vybrid SoC's but is only really useful in dual core configurations (VF6xx
+which comes with a Cortex-A5/Cortex-M4 combination).
+
+Required properties:
+- compatible: "fsl,vf610-mscm-ir"
+- reg: the register range of the MSCM Interrupt Router
+- fsl,cpucfg: The handle to the MSCM CPU configuration node, required
+ to get the current CPU ID
+- interrupt-controller: Identifies the node as an interrupt controller
+- #interrupt-cells: Two cells, interrupt number and cells.
+ The hardware interrupt number according to interrupt
+ assignment of the interrupt router is required.
+ Flags get passed only when using GIC as parent. Flags
+ encoding as documented by the GIC bindings.
+- interrupt-parent: Should be the phandle for the interrupt controller of
+ the CPU the device tree is intended to be used on. This
+ is either the node of the GIC or NVIC controller.
+
+Example:
+ mscm_ir: interrupt-controller@40001800 {
+ compatible = "fsl,vf610-mscm-ir";
+ reg = <0x40001800 0x400>;
+ fsl,cpucfg = <&mscm_cpucfg>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ interrupt-parent = <&intc>;
+ }
