The first patch prevents the ACPI core from attempting to map IRQ resources with a valid ResourceSource as GSIs. The first patch adds support for ResourceSource/IRQ domain mapping and fixes IRQ probe deferral by allowing platform_device IRQ resources to be re-initialized from the corresponding ACPI IRQ resource. Both changes described above are conditional on the ACPI_GENERIC_GSI config. The third patch takes advantage of the new capabilities to implement the driver for the IRQ combiners. Tested on top of v4.9. Changes V8 -> V9: * Do not attempt the mapping for non-GSI IRQs during bus scan. * Make some public APIs private to drivers/acpi/irq.c since they are no longer used on other modules. Changes V7 -> V8: * Reorder patches to allow all new code to be under drivers/acpi/irq.c. * Change acpi_irq_get implementation to be more similar to of_irq_get to improve maintainability.
