Hi Robin, Apologies, I did not really check which cluster is described for the 5410 (since 5422 boots from the A7). Should I define both pmu nodes (w/o interrupt affinity) in the exynos54xx,dtsi, and set the status property to "disabled"? And then add the interrupt affinity to the SoC variant, an

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 t
