Subject: [PATCH V3 0/2] irqchip: qcom: Add IRQ combiner driver
Date: Fri, 13 May 2016 12:16:41 -0400	[thread overview]
Message-ID: <1463156203-10970-1-git-send-email-agustinv@codeaurora.org> (raw)

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
