Cover letter [PATCH v2 0/4] usb: musb: fix USB enumeration issue in OMAP3 platform
This series fixes the USB enumeration issue caused because of the controller not able to get a reference to the PHY because of incorrect binding in the board file.
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 v1:
*) Rebased to the latest mainline kernel
Changes from RFC
*) Changed the signature of usb_get_phy_by_name() not to use struct device *
