Other panels using dsi uses a simple
"	reg: true"

I think that would suffice here too.

Yes, because dsi-controller.yaml restricts it to a single entry. 
However, it's description says there can be more than 1 virtual channel 
for a device. In that case, it shouldn't be restricted in 
dsi-controller.yaml and the above with 'maxItems: 1' would be correct. 
So I'd keep this as-is.
