Subject: [PATCH 3/3] ARM: dts: SAMSUNG: Add aliases of UART nodes
This patch adds alias entries for UART nodes of all SoCs using
samsung-uart compatible UART controllers, so that the dependency on
probe order is removed and deterministic device naming is assured.
Signed-off-by: Tomasz Figa <t.figa@...sung.com>
