I'm still trying to figure out internally how I can get a VID/PID for
this driver. We thought we had a valid vendor ID we could use, based on
a JEDEC ID that we already have assigned, but upon further investigation
I don't think we have the right to derive an SDIO VID from that JEDEC
ID, so the whole process might take a bit of time.

In the meantime, may I suggest that we continue the review as if a valid
VID/PID was assigned? You can keep your "Reviewed-by" until we actually
have valid IDs. If we have to get in touch with external organizations,
it might take a few weeks or even months to get sorted, I have no idea
how long that process will be.

Alternatively, I could just drop the SDIO VID/PID and just rely on device
tree instead? That leaves the question of what the compatible string
should be. Rob Herring doesn't want a generic "silabs,greybus" string,
it must be a real product and we don't have that yet.

I'd be happy to take any input that helps make progress :)
