Subject: [PATCH v2 3/4] arm64: dts: qcom: monaco: add RAS error source nodes
Date: Mon, 20 Jul 2026 13:49:53 +0530	[thread overview]
Message-ID: <20260720081954.1858180-4-umang.chheda@oss.qualcomm.com> (raw)
In-Reply-To: <20260720081954.1858180-1-umang.chheda@oss.qualcomm.com>

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.
