No, that's generally how common provider/consumer style bindings work.

If we could do it again, I would not have mmc pwrseq binding. The
properties belong in the device's node. So don't generalize the mmc
pwrseq binding.

It's a kernel problem if the firmware says there's a device on a
'discoverable' bus and the kernel can't discover it. I know you have
the added complication of a device with 2 interfaces, but please,
let's solve one problem at a time.
