Subject: [PATCH 1/3] arm: dts: exynos: Add serial path for Rinato board to get earlycon support
Date: Mon, 16 Apr 2018 12:35:35 +0200 [thread overview]
Message-ID: <20180416103537.29518-1-m.szyprowski@samsung.com> (raw)
In-Reply-To: CGME20180416103544eucas1p2c393cdccdb79955b64e57ccc53456479@eucas1p2.samsung.com
Add 'chosen' node with 'stdout-path' property to instruct kernel which
serial driver should be used for kernel console/logs. This allows to
enable earlycon messages by adding just 'earlycon' parameter to kernel
command line.
