Support EHCI host driver used on Panasonic UniPhier platform. Since Device Tree is not supported on UniPhier yet, the base address of USB cores are passed from board files (platdevice.c). TODO for me: Move the base address to device trees. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Marek Vasut <marex@denx.de>

|
|
The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
|
|
"high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
|
|
If your USB host controller supports USB 2.0, you will likely want to
|
|
configure this Host Controller Driver.
|
|
|
|
EHCI controllers are packaged with "companion" host controllers (OHCI
|
|
or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
|
|
will connect to EHCI if the device is high speed, otherwise they
|
|
connect to a companion controller. If you configure EHCI, you should
|
|
probably configure the OHCI (for NEC and some other vendors) USB Host
|
|
Controller Driver or UHCI (for Via motherboards) Host Controller
|
|
Driver too.
