So you are saying that because the current linux MTD stuff can only
probe (which doesn't always work), we should not put the proper chip
interface type in the device-tree ?

Your argument makes no sense to me.

Put the proper interface informations in the device-tree, maybe some OS
smarter than linux will make good use on it and maybe linux will be
fixed at one point too (not by you, of course, you gave us that line
often enough about not being paid to do the right thing).
