The chip node name in this driver is expected to be different and should
be prefixed with onenand instead of the regular "flash" string, so
mention it.

I don't think it is worth enforcing node names that we 
haven't defined in the spec. Wouldn't 'nand-controller' be appropriate?

Actually I've added this pattern here because there are several users in
the arm/boot/dts/ directory which use it, and the example below in this
file also uses onenand@xxx.

I can either fix the example to use nand-controller or add this pattern
(I guess "deprecated: true" would not mean anything?). What do you
prefer?

If we decide to switch to the nand-controller@ name, shall I change the
DTS as well?

Thanks,
Miquèl

I guess I'd just leave it as you have it.
