Cover letter [PATCH v3 0/4] ARM: Exynos4: Add irq domain and device tree support for wakeup interrupts
Quoted 19 lines · Thomas Abraham

Changes since v2:
- Reworked irq domain support based on v5 of the irq_domain generalization patches.

Changes since v1: (only patch 4/4 has changes)
- Fixes based on Rob's comments:
a. Fixed the function prototype of exynos4_init_irq_eint(void) b. Included interrupt-parent as an optional property for wakeup interrupt
controller node.

Samsung Exynos4 includes 32 external wakeup interrupt sources. The first 16 of these interrupts are connected to GIC SPI[31:16]. The last 16 of these interrupts are grouped together into one interrupt and connected to GIC SPI[32].

This patchset adds irq domain and device tree support for these interrupts. Since there are users of fixed linux irq numbers of the external wakeup interrupts, the legacy mapping is used for the irq domain.

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]

This patchset should be applied after applying the following patch. [PATCH] ARM: Exynos: Add irq domain and device tree support for interrupt combiner

Looks ok to me this series, but I lost above patch in my mail box. Thomas, could you please send updated it so that I can apply this series?

Thanks.

Best regards,
Kgene.
