am335x uses nop transceiver driver and need to enable builtin phy by writing into usb_ctrl register available in system control module register space. This is being added at musb glue driver layer until a separate system control module driver is available. Proper solution is to make use of control module driver, but it is not expected to be ready soon. Other options available are providing control module register space as memory resource via DT or using omap hwmod. DT approach has been rejected by Rob Herring, while resources are being moved from hwmod to DT. And both of the above approaches require that control module registers be configured in wrapper itself requring a quirk in driver as well as DT or hwmod. Here another option is used, providing driver with control module register physical address. Even though this a hack, there is no other option left till control module driver is ready. As of now only am335x is using dsps wrapper, and so driver is made aware of am335x control module physical address. Please note that this is a temporary arrangment till omap control module driver is available.
