I think you can make a copy of SMDK dts and name it -odroidxu straightaway and work further with it. exynos5410-pinctrl.dtsi is used for generic SoC-wide pinctrl definitions, such as pin banks and pin groups. There should be no board-specific things defined in it. Instead respective board dts shoul= d have them. >=20 > What about graphics?

The 3D GPU is completely independent from display controllers, which ar= e standard Samsung IP blocks, so you should be able to get unaccelerated output using VP+Mixer+HDMI or FIMD+DP using existing drivers.
