Subject: [PATCH v7 26/38] firmware: arm_scmi: remove legacy scmi_sensor_ops protocol interface
Date:   Tue, 16 Mar 2021 12:48:51 +0000
Message-Id: <20210316124903.35011-27-cristian.marussi@arm.com>
In-Reply-To: <20210316124903.35011-1-cristian.marussi@arm.com>
References: <20210316124903.35011-1-cristian.marussi@arm.com>
Precedence: bulk

Now that all the SCMI driver users have been migrated to the new interface
remove the legacy interface and all the transient code.
