Subject: [PATCH v2 01/10] arm64: dts: freescale: Add the top level dtsi support for imx8dxl
From: Jacky Bai <ping.bai@....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.
