Subject: [PATCH V9 09/10] remoteproc: imx_rproc: ignore mapping vdev regions
Date: Thu, 21 Jan 2021 09:03:34 +0800	[thread overview]
Message-ID: <1611191015-22584-10-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1611191015-22584-1-git-send-email-peng.fan@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

vdev regions are vdev0vring0, vdev0vring1, vdevbuffer and similar.
They are handled by remoteproc common code, no need to map in imx
rproc driver.
