[RFC PATCH v4 08/13] genirq/msi: Add support for allocating single MSI for a device

2018-12-26 Thread Lokesh Vutla
Previously all msi for a device are allocated in one go by calling msi_domain_alloc_irq() from a bus layer. This might not be the case when a device is trying to allocate interrupts dynamically based on a request to it. So introduce msi_domain_alloc/free_irq() apis to allocate a single msi.
