a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

The remove callbacks of EHCI drivers are often just a wrapper of
ehci_deregister.

17b68b5a58 dm: atmel: Add driver model support for the ehci driver
Add driver model support while retaining the existing legacy code.
This allows the driver to support boards that have converted to
driver model as well as those that have not.

676ae068d9 usb: ehci: rework to take advantage of new lowlevel interface
Kill off ehci-core.h
It was used to specify some static controller data. To support more than
one controller being active at any time we have to carry the controller
data ourselfes. Change the ehci interface accordingly.

NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed
to do the same thing as other platforms. But the change for now is at least
compile clean.

cc30b7803d Atmel : usb : add EHCI driver for Atmel SoC
Some Atmel SoC support USB EHCI, add the EHCI driver to support it.

To enable the USB EHCI, add the following configuration options into
board relative configuration file and remove USB OHCI options.

    #define CONFIG_USB_EHCI
    #define CONFIG_USB_EHCI_ATMEL
    #define CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS     2
