[PATCH 0/4] usb: phy: generic: Support enabling/disabling VBUS

[Sean Anderson]

The generic USB phy has had VBUS-related code for a long time, but it
has always been broken, since the regulator was never gotten from the
device tree. However, the support itself seems not very useful, since
e.g.  usb_phy_vbus_on/off has no users and usb_phy_set_power is only
used by gadgets to make sure they don't draw too much current. Instead,
use the VBUS regulator to implement otg_set_vbus, which is called from
several drivers. This results in a change in semantics of VBUS, but
since support was always broken I don't think this will have any affect.
