[PATCH 1/3] dt-bindings: phy: uniphier-usb2: Add vbus-supply

[Kunihiko Hayashi]

UniPhier USB2 PHY controller can apply vbus-supply.
Add "vbus-supply" property to fix the following warning.

  uniphier-pro4-ace.dtb: usb-glue: phy@2: 'vbus-supply' does not match any of the regexes: 'pinctrl-[0-9]+'
      From schema: Documentation/devicetree/bindings/phy/socionext,uniphier-usb2-phy.yaml

[PATCH 2/3] dt-bindings: phy: uniphier-usb3ss: Treat vbus-supply as optional

[Kunihiko Hayashi]

The usb-device doesn't need "vbus-supply" property, so the property should
be removed from required.

Add missing "phy" reset-names to fix the following warning:

There is no ahci-phy in current sources...

As a separate commit, this oneOf should be converted into allOf:if:then:
cases which will enforce the resets per compatible.

Can you do that as well?

Oops, I'm going to add ahci controller to the existing devicetree,
but not yet. I shouldn't write the future warning in the commit message,
so I'll fix it.

Ok, I've found some examples using "allOf:if:them:" cases,
so I'll try to convert it with another commit.

For an example, you can take a look at (linux-next):

and clocks/clock-names properties.

Thanks for your suggestion.
I understand how to write it and am trying to convert the *-names to this case.

I also found such cases and some mistakes in the other phys (usb3 and pcie),
so I'll fix and resend them next.

Thank you,
