[PATCH v4 0/2] usb: host: ehci-platform: add support for optional external vbus supply

[Amelie Delaunay]

This patchset adds support for optional external vbus supply per port in
ehci-platform.

On some boards, especially when vbus supply requires large current,
and the charge pump on the PHY isn't enough, an external vbus power switch
per port may be used.

---
Changes in v4:
 * Address Roger Quadros comments: split dt-bindings and driver changes.
 * Address Robin Murphy comments: simplify vbus_spplies initialization.

Changes in v3:
 * Address Felipe Balbi comments: reduce indentation in
   ehci_platform_port_power.
 * Address Roger Quadros and Alan Stern comments: platforms can have one
   external vbus supply per port, so add support to get as many optional
   regulator as implemented ports on the host controller.

Changes in v2:
 * Address Roger Quadros comments: move regulator_enable/disable from
   ehci_platform_power_on/off to ehci_platform_port_power.
