aa25e446ce dt-bindings: usb: add #phy-cells to usb-nop-xceiv
Consumers of usb-nop-xceiv use the phy binding, but #phy-cells is missing
from the binding. This is probably because this binding predates the
common phy binding. So add #phy-cells as a required property. This should
not break any users as missing should be treated as 0 cells.

7bdea87a87 usb: phy: nop: device tree documentation for vbus
Enhance the phy documentation by adding 2 new optional bindings :
 - the vbus gpio, which detects usb insertion
 - the vbus regulator, which provides current drawn from the usb cable

6b1b0fe069 Documentation: usb: phy: nop: Fix the description of 'vcc-supply'
Since bd27fa44e13830d2b ("usb: phy: generic: Don't use regulator framework for
RESET line") we no longer model the reset line as a regulator supply, so
adapt the documentation accordingly.

bd27fa44e1 usb: phy: generic: Don't use regulator framework for RESET line
Modelling the RESET line as a regulator supply wasn't a good idea
as it kind of abuses the regulator framework and also makes adaptation
code more complex.

Instead, manage the RESET gpio line directly in the driver. Update
the device tree binding information.

This also makes us easy to migrate to a dedicated GPIO RESET controller
whenever it becomes available.
