Subject: [PATCH 1/8] arm64: dts: mediatek: cherry: Enable the System Companion Processor
Date: Thu, 21 Jul 2022 15:42:21 +0200 [thread overview]
Message-ID: <20220721134228.310178-2-angelogioacchino.delregno@collabora.com> (raw)
In-Reply-To: <20220721134228.310178-1-angelogioacchino.delregno@collabora.com>
MT8195 features a SCP like some other older SoCs, and Cherry uses it
for various tasks. Add the required pin configuration and DMA pool
and enable the node.
