Subject: [PATCH V3 4/7] remoteproc: imx_rproc: use devm_ioremap
Date: Fri,  4 Dec 2020 15:40:33 +0800	[thread overview]
Message-ID: <20201204074036.23870-5-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20201204074036.23870-1-peng.fan@oss.nxp.com>

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

We might need to map an region multiple times, becaue the region might
be shared between remote processors, such i.MX8QM with dual M4 cores.
So use devm_ioremap, not devm_ioremap_resource.
