Add support for IRQ combiners in the Top-level Control and Status Registers (TCSR) hardware block in Qualcomm Technologies chips. The first patch fixes 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. The core ACPI resource management code has been changed to lookup the IRQ domain when an IRQ resource indicates a ResourceSource, and register the IRQ on that domain, instead of a GSI. The third patch takes advantage of the new capabilities to implement the driver for the IRQ combiners. 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 Changes V4 -> V5: * Fix issues flagged by the 0-DAY build bot * Fix some minor style issues raised by Timur Changes V3 -> V4: * Add a DSDT device probe table that is used to probe DSDT IRQ chips as necessary when converting HW IRQs to Linux IRQs * Describe IRQ combiner registers as ACPI Register resources 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 | 1 + drivers/acpi/irqdomain.c | 119 +++++++++++++ drivers/acpi/resource.c | 80 ++++++++- drivers/base/platform.c | 9 +- drivers/irqchip/Kconfig | 8 + drivers/irqchip/Makefile | 1 + drivers/irqchip/qcom-irq-combiner.c | 337 ++++++++++++++++++++++++++++++++++++ include/linux/acpi.h | 32 ++++ 8 files changed, 577 insertions(+), 10 deletions(-) create mode 100644 drivers/acpi/irqdomain.c create mode 100644 drivers/irqchip/qcom-irq-combiner.c -- Qualcomm Datacenter Technologies, Inc. on behalf of the Qualcomm Technologies, Inc.
