[PATCH v3 0/5] USB4 mode programming for QMMPHY on X1E

[Konrad Dybcio <konradybcio@kernel.org>]

The USB43DP QMP PHY, as the name suggests, supports USB4 in addition to
DP/USB. This series provides the necessary plumbing to switch to that
mode of operation on hamoa/purwa.

This is achieved by exposing a third `struct phy *` for the USB4 sub-
PHY, which will be toggled by the USB4 router driver, living within the
Thunderbolt framework, which will be posted separately.

Find more details in the individual commit messages. Tested on a
X1E80100 CRD.

No external dependencies.
