From 4e164dc5fa512ad66355b583f1f70c602e4717d6 Mon Sep 17 00:00:00 2001 From: Chanho Park Date: Wed, 12 Dec 2012 14:02:49 +0900 Subject: irqchip: exynos-combiner: Correct combined IRQs for exynos4 This patch corrects combined IRQs for exynos4 series platform. The exynos4412 has four extra combined irq group and the exynos4212 has two more combined irqs than exynos4210. Each irq is mapped to IRQ_SPI(xx). Unfortunately, extra 4 combined IRQs isn't sequential. So, we need to map the irqs manually.

Firs of all, we need to fix IRQ_PMU correctly and to split pmu initialization of exynos from plat-samsung for easily defining it. The number of CPU cores and PMU irq numbers are vary according to soc types. So, we need to identify each soc type using soc_is_xxx function and to define the pmu irqs dynamically. For example, the exynos4412 has 4 cpu cores and pmus.
