Kevin,

Do we still need to set the dev.parent to omap_device_parent?

Nope.

I guess the default&platform_bus parent is good enough and
potentially the DSS children should be able to overwrite that.

Yes, now that we use PM domains, we don't need it.  I just sent a patch
to remove omap_device_parent.

But it's still not possible to create a custom parent-child hierarchy
with omap_devices. Or can I change the parent of a platform_device after
it has been created? (doesn't sound very clean even if I can)

Nope, it has to be done before platform_device_add.

Thanks to Ohad patch [1] that Tony has just resent, you can use the 
internal omap_device API and thus will be able to change the parent 
before the registration.
