Hi Paul

Turns out the datasheet is publicly available.

So you can at run-time configure the voltage. Page 2, register 24, bit
13.

So back to my last question. Can you address the PHY without using the
switch? Even if it has the wrong voltage?

If you can, you could set the correct voltage in the probe() function.
