Hi,
This patch enables support for ARM Performance Monitoring Units
available in Cortex-A7
and Cortex-A15 CPU cores for Exynos54xx SoCs (5410, 5420 and 5422/5800).
Exynos5410 currently has only Cortex-A7 nodes defined in the device tree,
so the Cortex-A15 PMU is defined in the exynos5420 device tree file.
Tested with perf on Odroid XU4 (Exynos5422):
armv7_cortex_a7 PMU driver: 5 counters available
armv7_cortex_a15 PMU driver: 7 counters available
Regards,
Marian
