Hi Marek, with this patch (linux-next-20171201) I get on odroid-X2 [ 0.671862] hw perfevents: no interrupt-affinity property for /pmu, guessing. [ 0.672242] hw perfevents: enabled with armv7_cortex_a9 PMU driver, 7 counters available [ 0.672618] hw perfevents: no interrupt-affinity property for /arm_pmu, guessing. [ 0.672696] genirq: Flags mismatch irq 38. 00010c00 (arm-pmu) vs. 00010c00 (arm-pmu) [ 0.672716] hw perfevents: unable to request IRQ38 for ARM PMU counters [ 0.672733] hw perfevents: /arm_pmu: failed to register PMU devices! [ 0.672761] armv7-pmu: probe of arm_pmu failed with error -16 without it [ 0.686817] hw perfevents: no interrupt-affinity property for /pmu, guessing. [ 0.687194] hw perfevents: enabled with armv7_cortex_a9 PMU driver, 7 counters available Looks like arm_pmu in exynos4412.dtsi doubles pmu from exynos4.dtsi. Gruß,

You are right. I swear that I've checked exynos4 dts before preparing my patch and didn't notice existing ARM PMU node there. This means that my patch has to be reverted/dropped then. Sorry for the noise. Best regards

No problem, I'll drop it and rebase my tree.
