FYI these .dts changes need to be queued separately by Benoit and
should be posted as a seprate series in general to avoid confusion.

Ok, thanks!
I posted this for review along with other code changes.

I will post them seperately to Benoit.

Please wait until the driver updates have been reviewed.

I was thinking of sending this dts patches seperately to benoit, so that we
can enable atleast 1/4 bit mode for our controller. Anyways, there is no
memory mapped specific binding used. Once, we get our driver updates
reviewed and *if* there is anything memory mapped specific added, I can
send them as a seperate patch. Anyways with spi nor  framework in sight the
driver uodates can go anyewhere and might take some time.
.
Does this sound Ok to you?
