irqchip/gic: Return IRQ_SET_MASK_OK_DONE in the set_affinity method 2016-02-19T15:42:29+00:00 Marc Zyngier marc.zyngier@arm.com 2016-02-19T15:00:29+00:00 0407daceedfed003eaacb850d06cbbe359348367 Moving an SPI around doesn't require any extra work from the rest of the stack, and specially not for MSI-generated SPIs. It is then worth returning IRQ_SET_MASK_OK_DONE instead of IRQ_SET_MASK_OK, and simplify the other irqchips that rely on this behaviour (GICv2m and Marvell's ODMI controller).

irqchip/mvebu-odmi: Add new driver for platform MSI on Marvell 7K/8K 2016-02-19T15:34:33+00:00 Thomas Petazzoni thomas.petazzoni@free-electrons.com 2016-02-19T13:34:43+00:00 c27f29bbbf02168c9b1e8ba0fe7a8cb917e5a50f This commits adds a new irqchip driver that handles the ODMI controller found on Marvell 7K/8K processors. The ODMI controller provide MSI interrupt functionality to on-board peripherals, much like the GIC-v2m.
