Added a new driver for the usb part of control module. This has an API to power on the USB2 phy and an API to write to the mailbox depending on whether MUSB has to act in host mode or in device mode. Writing to control module registers for doing the above task which was previously done in omap glue and in omap-usb2 phy is removed. Changes from RFC: * Used "#if IS_ENABLED(CONFIG_OMAP_CONTROL_USB)" instead of "#if (defined(CONFIG_OMAP_CONTROL_USB) || \ defined(CONFIG_OMAP_CONTROL_USB_MODULE))" * return "-EADDRNOTAVAIL" if devm_request_and_ioremap fails. * Removed the dt data from this patch series (I'll send that as a separate series). * added "ctrl_module" binding to usb otg glue and usb phy in the Documentaion. This binding is not planned to be used until an actual requirement for it arises. This series was developed on git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git xceiv Did basic enumeration testing in omap4 panda, omap4 sdp and omap3 beagle.
