[PATCH v2 3/4] arm64: dts: qcom: monaco: add RAS error source nodes
From: Umang Chheda
Date: Mon Jul 20 2026 - 04:20:49 EST
Add RAS error source nodes for the Monaco SoC.
Two processor error sources are described: a per-PE node covering the
L1/L2 cache hierarchy using a PPI, and two shared L3 cache nodes for
the two CPU clusters using SPIs.
