bus: Document special ranges of IVARs

2026-02-17T20:45:13+00:00

Some IVAR indices are special in that they have global meaning across
multiple buses where as other IVARs are always private to the local bus.
Try to document this a bit and add constants for the various ranges to
avoid future conflicts.

This is a no-op, but IVAR indices are now generally defined as enums
as that makes it easier to define them in terms of ranges.

sys: RealTek -> Realtek

2025-11-27T06:19:26+00:00

Realtek changed how it styled its name 25 or so years ago, but the old
style persisted in many places. These products use the new styling in
their datasheets.

mii: Change e1000phy (Marvell 88E1000) PHYs to disable power down / isolate

2025-05-01T03:00:56+00:00

The reset sequence doesn't clear the power down / isolate bits during
power up and configuration.  Change that to make sure things are
consistent.

If the PHY is initialised by something external (eg a bootloader,
config EEPROM driving a switch chip, etc) which sets the power down
and/or isolate bits in E1000_CR, then the reset path wouldn't
undo it and the PHY will look permanently down.  Even when we
configure autonegotiate or statically nail the port up, it's still
not coming out of the power mode.

Revert "mccomphy: add support for YT8531"

2025-04-03T02:26:58+00:00

The new code makes use of FDT/OFW types and interfaces, and obviously
fails to build on amd64. Revert to fix.
