Subject: [PATCH] arm64: dts: mediatek: Add smi_common node for MT8183
Date: Thu, 1 Oct 2020 18:28:23 +0200 [thread overview]
Message-ID: <20201001162823.3592352-1-enric.balletbo@collabora.com> (raw)
The SMI (Smart Multimedia Interface) Common is a bridge between the m4u
(Multimedia Memory Management Unit) and the Multimedia HW. This block is
needed to support different multimedia features, like display, video
decode, and camera. Also is needed to control the power domains of such
HW blocks.
