Hello, This is the second version of this series to rework interrupt management. Compare to the RFC sent a couple of months ago, I took a different approach for handling multiple action per IRQ. If the driver wants to use this feature, it has to explicitely request it by passing the flag IRQ_SHARED to the newly created functions ({request,setup}_irq_flags). This will prevent developpers to mix the interrupt by mistake. While I was working on it, I also took time to rework the interrupt management to: - Make distinction between GIC and IRQ management - Drop {request,setup}_dt_irq which is ARM specific and use the common one - Merge route and setup IRQ functions - Improve error checking Having generic IRQ function will avoid ifdery in driver code and will hopefully help to port new feature such as ACPI. This series is a dependencies for the ARM SMMU drivers (the V2 will be sent soon.
