Raspberry Pi uses a DWC2 USB controller and a SMSC USB Ethernet adaptor.
Driver model support for these is available.
This series does the following:
- Enable CONFIG_DM_ETH and CONFIG_DM_USB on Raspberry Pi
- Convert the MMC driver to driver model
- Convert the video driver to driver model
- Fixes a driver model video bug which accessed beyond the frame buffer
- Fixes start-up of MMC with driver model (e.g. at present it does not
support env_fat)
- Clean up a few loose ends
With Ethernet active the device list looks something like this:

Changes in v4:
- Add patches to convert video and MMC to driver model also
- Rebase to master
Changes in v3:
- Drop applied patches from series
- Drop patch to introduce usbethaddr for driver model
