2018-05-13	irqchip/mvebu-gicp: Use level-triggered MSIs between ICU and GICP	Marc Zyngier	1	-16/+17
	The ICU and GICP drivers are using an ugly side-band mechanism to find out about the "clear" doorbell when using level interrupts. Let's convert it to level-triggered MSIs, which result in a nice cleanup.

2017-06-23	irqchip/irq-mvebu-icu: Add new driver for Marvell ICU	Thomas Petazzoni	1	-0/+289
	The Marvell ICU unit is found in the CP110 block of the Marvell Armada 7K and 8K SoCs. It collects the wired interrupts of the devices located in the CP110 and turns them into SPI interrupts in the GIC located in the AP806 side of the SoC, by using a memory transaction. Until now, the ICU was configured in a static fashion by the firmware, and Linux was relying on this static configuration. By having Linux configure the ICU, we are more flexible, and we can allocate dynamically the GIC SPI interrupts only for devices that are actually in use. The driver was initially written by Hanna Hawa <hannah@marvell.com>.
