+Subject: [PATCH] usb: otg: make twl6030_usb as a comparator driver to
+ omap_usb2
+
+All the PHY configuration other than VBUS, ID GND and OTG SRP are removed
+from twl6030. The phy configurations are taken care by the dedicated
+usb2 phy driver. So twl6030 is made as comparator driver for VBUS and
+ID detection.

+Subject: [PATCH] usb: phy: add a new driver for omap usb2 phy
+
+All phy related programming like enabling/disabling the clocks, powering
+on/off the phy is taken care of by this driver. It is also used for OTG
+related functionality like srp.
+
+This also includes device tree support for usb2 phy driver and
+the documentation with device tree binding information is updated.
+
+Currently writing to control module register is taken care in this
+driver which will be removed once the control module driver is in place.

+drivers/usb/musb/Kconfig: remove the 'Glue Layer' choice.
+
+In the config.omap configuration, we're setting CONFIG_USB_MUSB_OMAP2PLUS
+to 'y' but after running the script to create our configuration file, it's
+set to 'm', even if 'y' is valid. This result in an invalid configuration
+and build failure (missing omap_musb_mailbox symbol in our kernel binary).
+
+Removing the choice entry make things work.
