Subject: [PATCH 7/8] remoteproc: imx_rproc: support i.MX7ULP
Date: Mon, 22 Mar 2021 16:12:42 +0800
Message-ID: <1616400763-16632-8-git-send-email-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <1616400763-16632-1-git-send-email-peng.fan@oss.nxp.com>

From: Peng Fan <peng.fan@nxp.com>

i.MX7ULP A7 core runs under control of M4 core, M4 core starts by ROM
and powers most serivces used by A7 core, so A7 core has no power to
start and stop M4 core.
