[U-Boot] [PATCH 00/20] arm: rpi: Enable USB and Ethernet driver model Raspberry Pi

[Simon Glass]

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 at 7e200000
 serial      [ + ]    |   |-- uart at 7e201000
 usb         [ + ]    |   `-- usb at 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.
