[PATCH v2 3/3] arm64: dts: freescale: add Nodebox v3 CPU Module
Vincent Jardin via B4 Relay
devnull+vjardin.free.fr at kernel.org
Mon Sep 7 10:13:41 PDT 2026
From: Vincent Jardin <vjardin at free.fr>
The Nodebox v3 is a Free Mobile CPU module built around the NXP
LX2160A (16x Cortex-A72, DPAA2).
The same .dtsi is used by the U-Boot port, so both Linux and
u-boot should not drift.
