Subject: [PATCH V5 0/2] irqchip: qcom: Add IRQ combiner driver
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
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
Changes V4 -> V5:
* Fix issues flagged by the 0-DAY build bot
* Fix some minor style issues raised by Timur
