[PATCH V12 06/10] remoteproc: imx_rproc: use devm_ioremap

From: <hidden>
Date: 2021-02-18 01:40:53
Also in: linux-arm-kernel, linux-remoteproc, lkml
Subsystem: remote processor (remoteproc) subsystem, the rest · Maintainers: Bjorn Andersson, Mathieu Poirier, Linus Torvalds

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.
