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:
- Move Raspberry Pi to use device tree control (u-boot-dtb.bin instead of u-boot.bin)
- Remove GPIO platform data (now uses device tree)
- Remove serial platform data (now uses device tree)
- Add 'ranges' support to simple-bus
- Convert the DWC2 USB driver to support driver model
- Convert the SMSC95XX USB Ethernet driver to support driver model
- Enable CONFIG_DM_ETH and CONFIG_DM_USB on Raspberry Pi
With Ethernet active the device list looks something like this:
U-Boot> dm tree Class Probed Name
root [ + ] root_driver simple_bus [ + ] |-- soc gpio [ ] | |-- gpio@7e200000 serial [ + ] | |-- uart@7e201000 usb [ + ] | `-- usb@7e980000 usb_hub [ + ] | `-- usb_hub usb_hub [ + ] | `-- usb_hub eth [ + ] | `-- smsc95xx_eth simple_bus [ ] `-- clocks
Raspberry Pi 2 is not converted as I do not have one to test at present.

I could really use the DM part of this patchset on SoCFPGA, can you maybe drop the rpi part and repost it, so that part can be mainlined please ?
