2014-02-22irqchip: armada-370-xp: Setup a chained handler for the MPICEzequiel Garcia-1/+7
The new Armada 375 and Armada 38x Marvell SoCs are based on Cortex-A9 CPU cores and use the ARM GIC as their main interrupt controller. However, for various purposes (wake-up from suspend, MSI interrupts), they have kept a separate MPIC interrupt controller, acting as a slave to the GIC. This MPIC was already used as the primary controller on previous Marvell SoCs, so this commit extends the existing driver to allow the MPIC to be used as a GIC slave.

2013-09-30irqchip: armada-370-xp: implement MSI supportThomas Petazzoni-0/+3
This commit introduces the support for the MSI interrupts in the armada-370-xp interrupt controller driver. It registers an MSI chip to the MSI chip registry, which will be used by the Marvell PCIe host controller driver. The MSI interrupts use the 16 high doorbells, and are therefore notified using IRQ1 of the main interrupt controller.
