[PATCH 2/2] arm64: dts: qcom: sm8550: add PPI interrupt partitions for the ARM PMUs
Posted by Neil Armstrong 1 month, 2 weeks ago
The PMUs shares the same per-cpu (PPI) interrupt, so declare the proper
interrupt partition maps and use the 4th interrupt cell to pass the
partition phandle for each ARM PMU node.
