Did the use of "console" get OK'd on the devicetree mailing list then?

I know we have this bug in the kernel DTs, but let's fix it here: 
phandle values should have <> around them:

		console = <&uart_d>;

In order to prevent the kernel and U-Boot DT files from diverging, can 
you copy the entire DT content from the kernel rather than just a 
subset, i.e.:

         uarta: serial at 70006000 {
                 compatible = "nvidia,tegra114-uart", "nvidia,tegra20-uart";
                 reg = <0x70006000 0x40>;
                 reg-shift = <2>;
                 interrupts = <GIC_SPI 36 IRQ_TYPE_LEVEL_HIGH>;
                 clocks = <&tegra_car TEGRA114_CLK_UARTA>;
                 resets = <&tegra_car 6>;
                 reset-names = "serial";
                 dmas = <&apbdma 8>, <&apbdma 8>;
                 dma-names = "rx", "tx";
                 status = "disabled";
         };
