I wonder - I said earlier today that this works absolutely fine without
modification with DT, so why are you messing about with it adding DT
support?

This is totally the wrong approach.  The idea is that this deals with
/devices/ and /devices/ only.  It groups up /devices/.

It's up to the add_component callback to the master device to decide
how to deal with that.

And this patch has me wondering if you even understand how to use
this...  The master bind/unbind callbacks are the ones which establish
the "card" based context with the subsystem.

Please, before buggering up this nicely designed implementation, please
/first/ look at the imx-drm rework which was posted back in early January
which illustrates how this is used in a DT context - which is something
I've already pointed you at once today already.
