[PATCH 2/2] arm64: dts: imx8mm: Add support for Data Modul i.MX8M Mini eDM SBC

Marek Vasut marex at denx.de
Sun Feb 20 16:17:38 PST 2022


Add support for Data Modul i.MX8M Mini eDM SBC board. This is an
evaluation board for various custom display units. Currently
supported are serial console, ethernet, eMMC, SD, PCIe, SPI NOR,
USB host and USB OTG.
