From: Jacky Bai <ping.bai@nxp.com>

The i.MX8DXL is a device targeting the automotive and industrial
market segments. The flexibility of the architecture allows for
use in a wide variety of general embedded applications. The chip
is designed to achieve both high performance and low power consumption.
The chip relies on the power efficient dual (2x) Cortex-A35 cluster.

Add the reserved memory node property for dsp reserved memory,
the wakeup-irq property for SCU node, the imx ion, the rpmsg and the
cm4 rproc support.

FIrst of all, did you run make dt_binding_check?
I wonder there're dt binding missing for a few nodes
