Yes, that is right.

Frankly, I am really surprised and shocked at the cavalier attitude
expressed here WRT DT bindings in released kernels. Think about the
*users* of this code. Not everyone working with ARM Linux is a kernel
developer or a DT guru. There is really no indication at all that the
ARM Linux DT stuff released so far are not stable and trustworthy.

It is not nice to provide such a mess, and the idea that we *must*
have a mess because the whole system in still in development is bogus,
IMHO. Just make sure that the mainline kernel is really working and
that the DT bindings *there* are for keeps.

It is your job as kernel developers.

Thanks,
Richard
