Subject: [PATCH V12 0/3] irqchip: qcom: Add IRQ combiner driver
Date: Thu, 2 Feb 2017 18:23:56 -0500 [thread overview]
Message-ID: <1486077839-25547-1-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 prevents the ACPI core from attempting to map IRQ resources
with a valid ResourceSource as GSIs.
The second patch adds support for ResourceSource/IRQ domain mapping and
fixes IRQ probe deferral by allowing platform_device IRQ resources to be
re-initialized from the corresponding ACPI IRQ resource.
Both changes described above 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 v4.10-rc6.
Changes V11 -> V12:
* Remove probe table, add that optimization later.
* Fix some minor style issues.
Changes V10 -> V11:
* Add probe table and use it to implement driver presence detection.
* Fix kernel doc formatting in drivers/acpi/irq.c and some minor style issues.
* Minor bug fixes in the driver.
Changes V9 -> V10:
* Add checks for the producer_consumer field to not use produced IRQ
resources as consumed.
* Minor bug fixes in the driver.
Changes V8 -> V9:
* Do not attempt the mapping for non-GSI IRQs during bus scan.
* Make some public APIs private to drivers/acpi/irq.c since they are no
longer used on other modules.
