Subject: [PATCH v2 3/5] dt-bindings: remoteproc: Add the documentation for Meson AO ARC rproc
Date: Sat, 2 Jan 2021 21:59:02 +0100 [thread overview]
Message-ID: <20210102205904.2691120-4-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20210102205904.2691120-1-martin.blumenstingl@googlemail.com>
Amlogic Meson6, Meson8, Meson8b and Meson8m2 SoCs embed an ARC EM4
controller for always-on operations, typically used for managing system
suspend.

+
+description:
+ Amlogic Meson6, Meson8, Meson8b and Meson8m2 SoCs embed an ARC core
+ controller for always-on operations, typically used for managing
+ system suspend. Meson6 and older use a ARC core based on the ARCv1
+ ISA, while Meson8, Meson8b and Meson8m2 use an ARC EM4 (ARCv2 ISA)
+ core.
