ARM: dts: rockchip: add bootargs setting the correct serial console
From: Heiko Stuebner <heiko@...> Date: Mon, 4 Aug 2014 14:58:47 +0200
Commit-Message
Uart2 seems to be designated debug uart for all Rockchip platforms. On all rk30xx and rk31xx boards I've seen so far, this uart was used for the console and the rk3288 TRM even describes it as debug uart. Thus add it to the core SoC dtsi files to not duplicate the same information on every board. Signed-off-by: Heiko Stuebner <heiko@...>

This makes a multi_v7_defconfig-based kernel start sucessfully on my rk3188-radxarock and rk3288-evb arch/arm/boot/dts/rk3288.dtsi | 4 ++++ arch/arm/boot/dts/rk3xxx.dtsi | 4 ++++ 2 files changed, 8 insertions(+)
