Subject: [PATCH v4 17/37] firmware: arm_scmi: remove legacy scmi_power_ops protocol interface
Date:   Wed,  6 Jan 2021 20:15:50 +0000
Message-Id: <20210106201610.26538-18-cristian.marussi@arm.com>
In-Reply-To: <20210106201610.26538-1-cristian.marussi@arm.com>
References: <20210106201610.26538-1-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.
