[RFC PATCH 00/10 V3] MXS: Add i.MX28 USB Host driver

[Marek Vasut]

This patchset introduces the USB Host driver for i.MX28 CPU, utilising the
generic USB PHY infrastructure.

V2: Introduce stub imx-usb driver that then registers the PHY and EHCI drivers.
V3: Add the HCD on demand based on the PHY's state (only add HCD if it's host).
    Currently, only the HOST mode is supported.

Marek Vasut (10):
  MXS: Make clk_disable return integer
  MXS: Add USB EHCI and USB PHY clock handling
  MXS: Fixup i.MX233 USB base address name
  MXS: Add data shared between imx-usb and EHCI driver
  MXS: Add platform registration hooks for USB EHCI
  MXS: Add imx-usb driver
  MXS: Add USB PHY driver
  MXS: Add separate MXS EHCI HCD driver
  MXS: Enable USB on M28EVK
  MXS: Enable USB on MX28EVK
