[PATCH v4 1/5] arm: dts: Add IOT2050 device tree files
Jan Kiszka
jan.kiszka at siemens.com
Fri Jul 30 20:21:28 CEST 2021
From: Jan Kiszka <jan.kiszka at siemens.com>
Prepares for the addition of the IOT2050 board which is based on the TI
AM65x. The board comes in two variants, Basic and Advanced, so there are
separate dts files. Furthermore, the SPL has its own device tree.
Based on original board support by Le Jin, Gao Nian and Chao Zeng.
