From 2ae26f523e9bfcd3bdfa93604afe8de9addf5a90 Mon Sep 17 00:00:00 2001 From: Josef Schlehofer Date: Tue, 26 Jul 2022 14:31:26 +0200 Subject: mvebu: backport DTS changes for Turris Omnia from mvebu/dt My commit backported patches from the following links: - https://lore.kernel.org/linux-arm-kernel/20220704113622.18887-1-kabel@kernel.org/ - https://lore.kernel.org/linux-arm-kernel/20220704113622.18887-2-kabel@kernel.org/ According to the links, they are applied in repository mvebu in branch dt, so it should be included in upcoming Linux version soon.
