Subject: [PATCH v6 27/37] firmware: arm_scmi: port SystemPower protocol to new protocols interface
Date: Tue, 2 Feb 2021 22:15:45 +0000 [thread overview]
Message-ID: <20210202221555.41167-28-cristian.marussi@arm.com> (raw)
In-Reply-To: <20210202221555.41167-1-cristian.marussi@arm.com>
Convert internals of protocol implementation to use protocol handles and
expose a new protocol operations interface for SCMI driver using the new
get/put common operations.
Remove handle->system_priv now unused.
