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: https://github.com/r-vignesh/u-boot.git branch: usb
