This patch series enables ti dwc3 usb peripherial driver to adopt driver model and DT. And also adds support for to USB device boot using RNDIS for AM437x.
Tested on AM437x GP EVM in USB RNDIS boot mode. ROM downloads SPL, SPL loads U-Boot via usb ether and then U-Boot loads kernel image using the same interface.
Based on previous work submitted by Mugunthan here: https://lists.denx.de/pipermail/u-boot/2016-March/250115.html
