From 2c06e0797c32997a2ea9d1458bcdbb97c7090406 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Fri, 28 Feb 2025 09:40:26 +0100 Subject: [PATCH] arm64: dts: qcom: sm8650: add PPI interrupt partitions for the ARM PMUs 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.
