There is a newer version of this series
[PATCH v2 2/3] arm64: dts: imx8mp pollux: add expansion board overlay
Posted by Yannic Moog 1 week ago 
An expansion board (PEB-AV-10) may be connected to the
imx8mp-phyboard-pollux. Its main purpose is to provide multimedia
interfaces, featuring a 3.5mm headphone jack, a USB-A port and LVDS as
well as backlight connectors.
