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.
