From 1bf42507028a85b57260d00be2c33f5012bd3210 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 10 Jul 2015 13:53:59 +0900 Subject: [PATCH] ARM: dts: UniPhier: add on-chip UART device nodes The UniPhier on-chip UART driver was merged into the mainline by commit 1a8d2903cb6a ("serial: 8250_uniphier: add UniPhier serial driver"). Add device nodes to make it really available. We no longer have to depend on the on-board UART device (16550A), so let's change the chosen and aliases to point to the on-chip ones. Also, turn on the on-board Ethernet device.
