Subject: [PATCH 2/5] arm64: dts: qcom: Add Kalambo SoC
Date: Sat, 18 Jul 2026 05:06:22 -0700 [thread overview]
Message-ID: <20260718-b4-kalambo-crd-v1-2-a1069b5a2757@oss.qualcomm.com> (raw)
In-Reply-To: <20260718-b4-kalambo-crd-v1-0-a1069b5a2757@oss.qualcomm.com>
Introduce support for the Qualcomm Kalambo SoC. It is derived from Mahua
with CPU cluster 0 removed, leaving it with just cluster 1. As a result,
the PDP mailbox and SCP low-priority register windows are updated to
match the reduced CPU complex. Everything else should work as-is.
Add a label to the Glymur cluster0 cpu-map node to allow its removal on
derived SoCs.
