Raspberry Pi uses a DWC2 USB controller and a SMSC USB Ethernet adaptor. Neither of these currently support driver model.
This series does the following:

I'd strongly prefer not to do this. For one thing, it means we'd need different U-Boot builds for each of the different RPi models, and we currently don't need that (or perhaps we require users to create their own u-boot-dtb.bin by choosing the right DTB to append). If it
Why does device tree change how things work now? The get_board_rev() function currently deals with this. It doesn't look like rpi_board_rev is used anywhere else.
absolutely must be done, please note that there are many more RPi models than there are currently DT files for in the upstream kernel. I keep meaning to add a complete set of DT files to the kernel, but haven't gotten around to it yet. Take a look at board/raspberrypi/rpi/rpi.c:models[] for a likely list of the different DTs we'd need.
I've only added two - one for Raspberry Pi, and one for Raspberry Pi 2 (patches not sent yet, but at u-boot-dm/rpi-working)
