Anatolij Gustschin 230f7ede6c USB: add USB EHCI support for MPC5121 SoC 
Extends FSL EHCI platform driver glue layer to support
MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI
registers are in big endian format. The appropriate flags
are set using the information in the platform data structure.
MPC83xx system interface registers are not available on
MPC512x, so the access to these registers is isolated in
MPC512x case. Furthermore the USB controller clocks
must be enabled before 512x register accesses which is
done by providing platform specific init callback.

The MPC512x internal USB PHY doesn't provide supply voltage.
For boards using different power switches allow specifying
DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal
PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault"
properties in the device tree USB nodes. Adds documentation
for this new device tree bindings.

config USB_C67X00_HCD
tristate "Cypress C67x00 HCD support"
depends on USB
help
The Cypress C67x00 (EZ-Host/EZ-OTG) chips are dual-role
host/peripheral/OTG USB controllers.
Enable this option to support this chip in host controller mode.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called c67x00.
config USB_XHCI_HCD
tristate "xHCI HCD (USB 3.0) support (EXPERIMENTAL)"
depends on USB && PCI && EXPERIMENTAL
---help---
The eXtensible Host Controller Interface (xHCI) is standard for USB 3.0
"SuperSpeed" host controller hardware.
To compile this driver as a module, choose M here: the
module will be called xhci-hcd.
config USB_XHCI_HCD_DEBUGGING
bool "Debugging for the xHCI host controller"
depends on USB_XHCI_HCD
---help---
Say 'Y' to turn on debugging for the xHCI host controller driver.
This will spew debugging output, even in interrupt context.
This should only be used for debugging xHCI driver bugs.
If unsure, say N.
config USB_EHCI_HCD
tristate "EHCI HCD (USB 2.0) support"
depends on USB && USB_ARCH_HAS_EHCI
---help---
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.
You may want to read <file:Documentation/usb/ehci.txt>.
To compile this driver as a module, choose M here: the
module will be called ehci-hcd.
config USB_EHCI_ROOT_HUB_TT
bool "Root Hub Transaction Translators"
depends on USB_EHCI_HCD
---help---
Some EHCI chips have vendor-specific extensions to integrate
transaction translators, so that no OHCI or UHCI companion
controller is needed. It's safe to say "y" even if your
controller doesn't support this feature.
This supports the EHCI implementation that's originally
from ARC, and has since changed hands a few times.
config USB_EHCI_TT_NEWSCHED
bool "Improved Transaction Translator scheduling"
depends on USB_EHCI_HCD
default y
---help---
This changes the periodic scheduling code to fill more of the low
and full speed bandwidth available from the Transaction Translator
(TT) in USB 2.0 hubs. Without this, only one transfer will be
issued in each microframe, significantly reducing the number of
periodic low/fullspeed transfers possible.
If you have multiple periodic low/fullspeed devices connected to a
highspeed USB hub which is connected to a highspeed USB Host
Controller, and some of those devices will not work correctly
(possibly due to "ENOSPC" or "-28" errors), say Y. Conversely, if
you have only one such device and it doesn't work, you could try
saying N.
If unsure, say Y.

The OXU210HP is an USB host/OTG/device controller. Enable this

This driver does not support isochronous transfers and doesn't
implement OTG nor USB device controllers.

---help---
The ISP1760 chip is a USB 2.0 host controller.
This driver does not support isochronous transfers or OTG.
This USB controller is usually attached to a non-DMA-Master
capable bus. NXP's eval kit brings this chip on PCI card

---help---
The Open Host Controller Interface (OHCI) is a standard for accessing
USB 1.1 host controller hardware. It does more in hardware than Intel's
UHCI specification. If your USB host controller follows the OHCI spec,
say Y. On most non-x86 systems, and on x86 hardware that's not using a
USB controller from Intel or VIA, this is appropriate. If your host
controller doesn't use PCI, this is probably appropriate. For a PCI
based system where you're not sure, the "lspci -v" entry will list the
right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.

The Universal Host Controller Interface is a standard by Intel for
accessing the USB hardware in the PC (which is also called the USB
host controller). If your USB host controller conforms to this
standard, you may want to say Y, but see below. All recent boards
with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
i810, i820) conform to this standard. Also all VIA PCI chipsets
(like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro

config USB_U132_HCD
tristate "Elan U132 Adapter Host Controller"
depends on USB && USB_FTDI_ELAN
default M
help
The U132 adapter is a USB to CardBus adapter specifically designed
for PC cards that contain an OHCI host controller. Typical PC cards
are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
adapter will *NOT* work with PC cards that do not contain an OHCI
controller.
For those PC cards that contain multiple OHCI controllers only the
first one is used.
The driver consists of two modules, the "ftdi-elan" module is a
USB client driver that interfaces to the FTDI chip within ELAN's
USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
controller driver that talks to the OHCI controller within the
CardBus cards that are inserted in the U132 adapter.
This driver has been tested with a CardBus OHCI USB adapter, and
worked with a USB PEN Drive inserted into the first USB port of
the PCCARD. A rather pointless thing to do, but useful for testing.
It is safe to say M here.
