Subject: [PATCH] dt-bindings: remoteproc: mtk,scp: Allow multiple memory regions
Date: Wed, 6 May 2026 21:31:57 +0800 [thread overview]
Message-ID: <20260506133157.3283204-1-arnab.layek@mediatek.com> (raw)
Update the memory-region property to support 1-2 reserved memory
regions instead of exactly one. This is needed for newer MediaTek
SoCs like MT8188 which require additional memory regions for SCP
operation.
Tested on MT8188 Geralt platform.
