Subject: [PATCH v3 0/4] usb: phy: generic: Support enabling/disabling VBUS
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.
This series is pretty unpopular... I only got minor feedback on one
patch last time. I'll try to remember to ping when the merge window
opens up.
Changes in v3:
- Update description as suggested by Linus
Changes in v2:
- Fix dt_binding_check errors
Sean Anderson (4):
dt-bindings: usb: usb-nop-xceiv: Repurpose vbus-regulator
usb: phy: generic: Get the vbus supply
usb: phy: generic: Implement otg->set_vbus
usb: phy: generic: Disable vbus on removal
