Subject: [PATCH v4 01/13] ASoC: mediatek: common: add SMC ops and SMC CMD
Date:   Fri, 30 Dec 2022 13:54:31 +0800
Message-ID: <20221230055443.16024-2-trevor.wu@mediatek.com>
In-Reply-To: <20221230055443.16024-1-trevor.wu@mediatek.com>
References: <20221230055443.16024-1-trevor.wu@mediatek.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

SMC call is required to communicate with ATF for some secure operations,
so we add SMC ops IDs and SMC CMD ID to common header.
