The first patch fixes IRQ probe deferral by allowing platform_device IRQ resources to be re-initialized if the ACPI core failed to find the IRQ domain during ACPI bus scan. The second patch adds support for ResourceSource/IRQ domain mapping when using Extended IRQ Resources with a specific ResourceSource. These changes 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-rc4. Changes V6 -> V7: * Consolidate changes for ResourceSource/IRQ domain mapping to the same source file implementing the generic GSI support, making it conditional on CONFIG_ACPI_GENERIC_GSI. * Eliminate some code duplication by implementing acpi_register_gsi in terms of the new acpi_register_irq API. Changes V5 -> V6: * Drop probe table and on-demand probing based on resource_source * Add patch to fix probe deferral * Change back combiner driver to use the platform_device/platform_driver APIs Agustin Vega-Frias (3): ACPI: Retry IRQ conversion if it failed previously ACPI: Add support for ResourceSource/IRQ domain mapping irqchip: qcom: Add IRQ combiner driver drivers/acpi/Makefile | 2 +- drivers/acpi/{gsi.c => irq.c} | 98 +++++++++-- drivers/acpi/resource.c | 88 ++++++++-- drivers/base/platform.c | 9 +- drivers/irqchip/Kconfig | 8 + drivers/irqchip/Makefile | 1 + drivers/irqchip/qcom-irq-combiner.c | 337 ++++++++++++++++++++++++++++++++++++ include/linux/acpi.h | 26 +++ 8 files changed, 541 insertions(+), 28 deletions(-) rename drivers/acpi/{gsi.c => irq.c} (53%) create mode 100644 drivers/irqchip/qcom-irq-combiner.c -- Qualcomm Datacenter Technologies, Inc. on behalf of the Qualcomm Technologies, Inc.
