Subject: [PATCH V6 0/3] irqchip: qcom: Add IRQ combiner driver
Date: Fri, 28 Oct 2016 16:48:13 -0400 [thread overview]
Message-ID: <1477687696-1509-1-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 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
