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.
