Subject: [PATCH v12 11/11] arm64: dts: mediatek: mt8195: Add SCP 2nd core
Date: Wed, 17 May 2023 12:34:49 +0800 [thread overview]
Message-ID: <20230517043449.26352-12-tinghan.shen@mediatek.com> (raw)
In-Reply-To: <20230517043449.26352-1-tinghan.shen@mediatek.com>
Rewrite the MT8195 SCP device node as a cluster and
add the SCP 2nd core in it.
Since the SCP device node is changed to multi-core structure,
enable SCP cluster to enable probing SCP core 0.
