Subject: [PATCH 11/22] firmware: arm_scmi: Add SCMIv3.1 extended names protocols support
Date: Wed, 30 Mar 2022 16:05:40 +0100 [thread overview]
Message-ID: <20220330150551.2573938-12-cristian.marussi@arm.com> (raw)
In-Reply-To: <20220330150551.2573938-1-cristian.marussi@arm.com>
Using the common protocol helper implementation add support for all new
SCMIv3.1 extended names commands related to all protocols with the
exception of SENSOR_AXIS_GET_NAME.
