Subject[PATCH 1/2] ARM: dts: imx6q: add pmu interrupt-affinity
Date
Explicitly specify interrupt affinity to avoid HW perfevents
need to guess. This avoids the following error upon boot:
hw perfevents: no interrupt-affinity property for /pmu, guessing.

Specifying all four CPUs shows no aversive effects on i.MX 6Dual
SoCs.
