Subject: [PATCH v4 0/2] ARM: Exynos: Add irq_domain and device tree support for combiner
Date: Tue, 21 Feb 2012 10:03:24 +0530 [thread overview]
Message-ID: <1329798806-32482-1-git-send-email-thomas.abraham@linaro.org> (raw)
Changes since v3:
- In dt case, the use of fixed gic linux irq number to map the combiner
interrupt output is removed. This is replaced with the interrupt number
obtained from the gic irq domain. (Thanks to Rob Herring and Grant
Likely for this suggestion).
- Split the patch into two parts - irq_domain and device tree support
addition.
Changes since v2:
- Rebased to Grant's irqdomain/next branch.
Changes since v1:
- Includes all changes suggested by Rob Herring.
- Tested with SPARSE_IRQ enabled.
This patchset adds irq_domain and device tree support for the Exynos Interrupt
Combiner controller.
The first patch adds a common irq domain for the interrupts managed by the
interrupt combiners. All the instances of irq combiner reference the common irq
domain for translating hardware interrupts to linux irq number.
The second patch adds a interrupt specifier translator to support device tree
based instantiation. It can translate interrupt specifiers for device nodes
which use combiner as their interrupt parent.
This patchset is based on
http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git [for-next]
with all irq_domain (v5) patches merged from
http://git.secretlab.ca/git/linux-2.6.git [irqdomain/next]
