Subject: [PATCH V2 4/7] remoteproc: imx_rproc: use devm_ioremap
Date: Sun, 27 Sep 2020 14:41:28 +0800 [thread overview]
Message-ID: <20200927064131.24101-5-peng.fan@nxp.com> (raw)
In-Reply-To: <20200927064131.24101-1-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.
