mt65xx USB3.0 PHY binding
MediaTek T-PHY binding
--------------------------
This binding describes a usb3.0 phy for mt65xx platforms of Medaitek SoC.
T-phy controller supports physical layer functionality for a number of

"mediatek,mt8173-u3phy";
make use of "mediatek,generic-tphy-v1" on mt2701 instead and
"mediatek,generic-tphy-v2" on mt2712 instead.

clock-specifier pairs, one for each entry in clock-names
- clock-names : (deprecated, use port's one instead) must contain

Regular case:

Some SoCs use one interrupt with the above muxed together, so for these
* "otg-mux" : otg-port interrupt, which mux otg-id/otg-bvalid/linestate
to one.
