Subject: [PATCH V13 06/10] remoteproc: imx_rproc: use devm_ioremap
Date: Sat, 6 Mar 2021 19:24:21 +0800 [thread overview]
Message-ID: <1615029865-23312-7-git-send-email-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <1615029865-23312-1-git-send-email-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.
