If only one supply, why not use panel-simple-dsi.yaml? Though probably 
there's more than just an IO supply?

Display regulators (AB/IBB/AMOLEDB, not to be confused with LAB/IBB)
on modern Qualcomm platforms are controlled by the secure firmware
layer (yes, you read that correctly). Some panels require additional
supplies, but this one just has one positive, one negative and one
I/O regulator.
