Subject: [PATCH 0/4] usb: musb: fix USB enumeration issue in OMAP3 platform

In the case of non-dt boot, the platform specific initialization file
(board file) will do usb_bind_phy that binds the usb controller with the
PHY using device names. After the device names are created using 
PLATFORM_DEVID_AUTO, our original method of binding by device names doesn't
work reliably (since the device name changes). Hence the usb controller
is made to use labels for getting the PHY.

Here the PHY name is added in the plat data of USB controller device which
should be used by the controller driver to get the PHY.
Two new APIs usb_get_phy_by_name and devm_usb_get_phy_by_name are added to
be used by the controller to get the PHY by name.

Changes from RFC
*) Changed the signature of usb_get_phy_by_name() not to use struct device *

Kishon Vijay Abraham I (4):
  arm: omap: Add phy binding info for musb in plat data
  usb: phy: add a new API to get PHY ref by label
  usb: musb: omap: use the new API to get PHY reference by label
  arm: omap: remove using usb_bind_phy for binding musb and phy
