Well, DT can be used with x86. I think Edison did that. But i assume
your PCIe host is in ACPI, not DT. So getting this linking working
will not be easy.

There has been some work to add an ACPI binding for PHYs. I don't know
if it actually got far enough that you can hack your DSDT to add a
PHY. But i'm sure it did not get far enough that you can describe an
MDIO bus in DSDT, so it probably is not going to help you.

Yes, or MIPS.
