Hi Olimpiu,

Oh, "arc" and "arctic" is totally different.
In my opinion, one of the purposes of DT is to describe hardware stuffs.
So, please use more detailed words.

DT is some kind of ABI. It means that changing DT names such as property names
is not easy, after DT patches were merged. So, if someone want to add new DT stuff
into the vanilla kernel, that patch should be reviewed more thoroughly
than normal patches about driver stuffs.
