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?

Regards,
Dongjin.

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.
