[PATCH 4/8] remoteproc: imx_rproc: use devm_ioremap
From: Peng Fan (OSS)
Date: Mon Dec 21 2020 - 04:58:05 EST
From: Peng Fan <peng.fan@xxxxxxx>
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.
