Subject: [PATCH V7 2/3] firmware: imx: add pm svc headfile
Date: Thu, 18 Oct 2018 17:26:01 +0000 [thread overview]
Message-ID: <1539883285-7990-3-git-send-email-aisheng.dong@nxp.com> (raw)
In-Reply-To: <1539883285-7990-1-git-send-email-aisheng.dong@nxp.com>
Add SCU PM SVC related protocol definitions which will be used by a number
of PM functions like Power Domain, Clock, Reset and etc. The detailed
implementation of each function will put in the individual function drivers.
