The BeagleV Starlight v0.9 board[1] doesn't have the IRQB line routed to
the SoC, but it is still useful to be able to reach the PMIC over I2C

What is still useful?

I can't say that I've been keeping up with the latest DT binding

Or are optional properties omitted from documentation?

Optional properties are the ones not listed in the 'required' list.
