Subject: [PATCH] arm64: dts: specify console via command line
Date: Thu, 5 Mar 2020 17:06:35 +0800 [thread overview]
Message-ID: <20200305090635.30569-1-zhang.lyra@gmail.com> (raw)
From: Chunyan Zhang <chunyan.zhang@unisoc.com>
The SPRD serial driver need to know which port would be used as console
in an early period during initialization, otherwise console init would
fail since we added this feature[1].
So this patch add console to command line via devicetree.
