That checkpatch warning is known to have false positives in cases where
the binding says "<CHIPNAME>-device" or "device-<VERSION>".  If you want
to update the binding to give an example with a version, that's fine,
but checkpatch shouldn't be why.  We're not going to update the binding
example again to match a different version the next time one is added to
a device tree...

This is an example of why it's better to rely on version registers when
present.

Hi scott,

I can see this patch in "superseded" state in patchwork. As per our discussion the IP version checking is to be done by compatible string only, so can I proceed to send this patch again?

Sorry, apparently I thought that
http://patchwork.ozlabs.org/patch/383670/ was a newer version of the
patch, and didn't notice they were for different chips.  No need to
resend.  Thanks for pointing this out.
