Subject: [PATCH v2 02/12] arm64: dts: imx8qm-mek: fix reserved memory node names for remoteproc
Date: Wed, 29 Jul 2026 21:07:58 +0800 [thread overview]
Message-ID: <20260729-rproc-dts-v2-2-debbe0816202@nxp.com> (raw)
In-Reply-To: <20260729-rproc-dts-v2-0-debbe0816202@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
The imx_rproc driver uses node names to identify reserved memory regions.
It checks for "vdev0buffer" to skip mapping, "rsc-table" to locate the
resource table, and "vdev" prefix to filter vdev regions.
Rename the reserved memory nodes to use the expected names so the driver
can correctly identify and handle each region.
Fixes: 52c9971edd4f ("arm64: dts: imx8qm-mek: add cm4 remote-proc and related memory region")
