[PATCH v2 4/4] arm64: dts: qcom: lemans: add RAS error source nodes

From: Umang Chheda

Date: Mon Jul 20 2026 - 04:24:06 EST


Add RAS error source nodes for the Lemans 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.
