From: Jacky Bai <[email protected]>
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 rpmsg and the cm4 rproc
support.
