This series adds support for Cadence USB Host and Gadget controller
drivers. This is borrowed directly from Linux kernel v5.4-rc1.
Driver as such supports both 3.0 and 2.0 speeds. But USB 3.0 requires a
PHY driver which will be added in a separate follow series
Patch 7 adds TI wrapper driver for Cadence USB controller.
Both host and device mode has been tested on TI's J721e SoC. DFU, UMS
and fastboot gadgets have been tested.
Complete series (+ DT nodes required for J721e) can be found here:

I tested the series for Host and device operations on with a J721e-evm.
As expected, USB3 is not yet supported on the J721e because the driver
for the USB3 phy is not there yet.
