[PATCH v1 2/2] arm64: dts: freescale: verdin-imx8mm: add support to mallow board
From: Francesco Dolcini
Date: Fri Dec 01 2023 - 10:07:47 EST
From: Joao Paulo Goncalves <joao.goncalves@xxxxxxxxxxx>
Add Toradex Verdin IMX8MM Mallow carrier board support. Mallow is a
low-cost carrier board in the Verdin family with a small form factor and
build for volume production making it ideal for industrial and embedded
applications.
