on top of all that, for IPs which are used on many SoCs (such as MUSB)
it's quite silly to force all users to provide resources in a certain
order. It sounds to me that this will be prone to error in many ways
until everything is synced up and on the correct order.

Ditching _byname is a very bad idea.

I continue to disagree.  The current _byname is an abonimation and hack
to try to "fix" this problem.

_byname should have been implemented differently - rather than overriding
the resources name field (which is normally specified to be the device
or driver name), a new field should have been introduced in struct resource
to carry the resource sub-name (which is really what it is.)

That would have avoided making /proc/iomem completely illegible with
multiple devices using this feature.

I agree 100%.

Please clarify. 

What I hear Russell saying is a problem with the *implementation* of the
_byname API.  

What I hear you sating is that since DT doesn't support this, we need to
remove it's usage completely from platform_devices also.

These are two very different approaches.

Fixing the implementation as Russell suggested seems relatively easy,
and conceptually similar to adding it to the DT.  Removing _byname all
together seems like significant work just to avoid adding a feature to
the DT core.
