Subject: [PATCH] arm64: dts: allwinner: pine64: Add remaining UART aliases
Date: Fri, 14 Apr 2017 21:08:04 +0200 [thread overview]
Message-ID: <20170414190804.21865-1-afaerber@suse.de> (raw)
Enabling uart2 node currently leads to a /dev/ttyS1 device, with ttyS0..4
always present, causing confusion on the user's part.
dtc cannot resolve an overlay's &uart2 reference for strings, only for
phandles, so it would need to hardcode the full node path.
Avoid this and enforce reliable numbering by adding serialX aliases for:
UART1 - on Wifi/BT connector
UART2 - on Pi-2 connector
UART3 - on Euler connector
UART4 - on Euler connector
Signed-off-by: Andreas Färber <afaerber@suse.de>
