Subject: [PATCH V6 06/10] remoteproc: imx_rproc: use devm_ioremap
Date: Tue, 12 Jan 2021 17:39:15 +0800 [thread overview]
Message-ID: <1610444359-1857-7-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1610444359-1857-1-git-send-email-peng.fan@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.
