Usuually when the display IC is known, there's a fallback compatible for
it. Then 'renesas' vendor prefix on the properties makes more sense.

inversion. Perhaps renesas,column-inversion?

I would have expected contrast to be more than boolean. Is this
something any a-Si panel would support or somehow Renesas specific?
