Add support for IRQ combiners in the Top-level Control and Status Registers (TCSR) hardware block in Qualcomm Technologies chips.
The first 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 second patch takes advantage of the new capabilities to implement the driver for the IRQ combiners. Changes V1 -> V2: * Remove use of GPIO library for the combiner * Refactor to use fwnode/ResourceSource to IRQ domain mapping introduced in ACPI core Changes V2 -> V3: * Removed parsing of _PRS to find IRQs * Removed acpi_irq_domain_create and acpi_irq_domain_remove Agustin Vega-Frias (2): ACPI: Add support for ResourceSource/IRQ domain mapping irqchip: qcom: Add IRQ combiner driver drivers/acpi/Makefile | 1 + drivers/acpi/irqdomain.c | 108 +++++++++++ drivers/acpi/resource.c | 23 ++- drivers/irqchip/Kconfig | 8 + drivers/irqchip/Makefile | 1 + drivers/irqchip/qcom-irq-combiner.c | 344 ++++++++++++++++++++++++++++++++++++ include/linux/acpi.h | 6 + 7 files changed, 483 insertions(+), 8 deletions(-) create mode 100644 drivers/acpi/irqdomain.c create mode 100644 drivers/irqchip/qcom-irq-combiner.c -- Qualcomm Innovation Center, Inc.
