This patchset fixes irq numbers of ARM Performance Monitoring unit and enable it
for Perf(Performance Counter) on the exynos 4 and 5. The exynos4 and 5 use 2
more cpu cores which has its own pmu.
The exynos uses combiner-irq type for arm-pmu. Especially, the exynos4412 has 4
extra combined irq groups. So, we need to change a max combiner number.
To enable perf, we need also to implement a set_irq_affinity function about the
combiner-irq. After applying this patch, we can use the perf for the exynos
machine.
Changes from v2:
- Convert to dt binding of exynos5250
Changes from v1:
- Split arm-pmu init of exynos from plat-samsung
- Correct combined irqs of exynos4412
- Use soc_is_xxx function instead of CONFIG_XXX to identify dynamically
