arm64: dts: qcom: Drop CPU masks from GICv3 PPI interrupts

2026-03-26T14:40:59+00:00

Unlike older GIC variants, the GICv3 DT bindings do not support specifying a CPU mask in PPI interrupt specifiers. Drop the masks.

arm64: dts: qcom: Split PMU nodes for heterogeneous CPUs

2024-05-28T21:07:35+00:00

Arm heterogeneous configurations should have separate PMU nodes for each CPU uarch as the uarch specific events can be different. The "arm,armv8-pmuv3" compatible is also intended for s/w models rather than specific uarch implementations. All the kryo CPUs are missing PMU compatibles, so they can't be fixed.
