Subject: [PATCH 1/2] ARM: dts: exynos: Use stdout-path property instead of console in bootargs
Date: Mon,  8 Apr 2019 07:19:25 +0200	[thread overview]
Message-ID: <20190408051926.462-1-krzk@kernel.org> (raw)

Replacing bootargs with stdout-path property in chosen node allows using
early console by adding just 'earlycon' parameter to the kernel command
line.
