[Jimmychea]

Each reference board has a standard device tree as follows:

imx8mp-evk.dts single or multiple displays with HDMI, MIPIDSI-HDMI, and LVDS-H

Take the following as example is with special function:

imx8mp-ab2.dtb: audio board
 imx8mp-evk-sof-wm8960.dtb: Sound open firmware for WM8960
audio

Details you can see in the i.MX Linux Release Notes document.
