Subject: arm64: zynqmp: add pmu interrupt-affinity
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7cfddb4c07332fbe0968de48c00f4463bcda5e8b;p=u-boot.git

arm64: zynqmp: add pmu interrupt-affinity

Explicitly specify interrupt affinity to avoid HW perfevents
need to guess. This avoids the following error upon linux boot:
armv8-pmu pmu: hw perfevents: no interrupt-affinity property,
guessing.
