Subject: [PATCH V8 0/3] irqchip: qcom: Add IRQ combiner driver
Date: Tue, 29 Nov 2016 17:57:36 -0500 [thread overview]
Message-ID: <1480460259-8585-1-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 patch prevents the ACPI core from attempting to map IRQ resources
with a valid ResourceSource as GSIs.
The second patch fixes IRQ 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.
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 v4.9-rc7.
Changes V7 -> V8:
* Reorder patches to allow all new code to be under drivers/acpi/irq.c.
* Change acpi_irq_get implementation to be more similar to of_irq_get
to improve maintainability.
Changes V6 -> V7:
* Consolidate changes for ResourceSource/IRQ domain mapping to the same
source file implementing the generic GSI support, making it conditional
on CONFIG_ACPI_GENERIC_GSI.
* Eliminate some code duplication by implementing acpi_register_gsi in
terms of the new acpi_register_irq API.
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
