Subject: [PATCH V9 0/3] irqchip: qcom: Add IRQ combiner driver
Date: Wed, 14 Dec 2016 17:10:35 -0500 [thread overview]
Message-ID: <1481753438-3905-1-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 first 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 v4.9.
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.
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.
