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.
