[PATCH v2 00/12] arm64: dts: freescale: fix reserved memory node names for remoteproc

[PATCH v2 00/12] arm64: dts: freescale: fix reserved memory node names for remoteproc

[Peng Fan (OSS)]

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. Several i.MX
board dts files used incorrect node names (e.g. "vdevbuffer",
"memory-rsc-table", "memory@..."), causing the driver to fail these
checks.

This series renames the reserved memory nodes across all affected boards
to use the expected names.

[PATCH v2 07/12] arm64: dts: imx93-11x11-frdm: fix reserved memory node names for remoteproc

[Peng Fan (OSS)]

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

The imx_rproc driver checks for the name "vdev0buffer" to skip mapping
the vdev buffer region, as it is handled by rproc_add_virtio_dev.
With the node named "vdevbuffer", the check fails and the region gets
unnecessarily mapped. Rename it to "vdev0buffer" to match what the
driver expects.

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.
