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

 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 ?

Half of this series in in dm/master - please rebase on top of that.

You asking people to rebased on top of dm/master has become quite common recently ;-)

I hope to get a pull request out by Friday,

Excellent, I'll wait until this stuff hits u-boot/master . Thanks!
