Hello,
I am trying to understand what I have to do for device tree.
In order to create dts file for ODROID-X hardware, it seems I may need dts file of EXYNOS4412 SoC. But maybe exynos4412.dtsi is not merged yet or not exist, like exynos4210.dtsi or exynos5250.dtsi. Obviously it seems not easy to create such a file without SoC datasheet, and I do not have it.
So do I wait for the file to be merged by Samsung or better to create initial dts file cloned from exynos4210.dtsi and modify to have verified nodes with the source/header files?
What's your suggestion?

Basic rule (that has some flexibility for legacy platforms) is that the net movement of board support should move from board files to device-tree based. Introduction of a brand new board like this is a prime example of something that should be using device tree from day 1.
