We can't use the generic usb_hcd_platform_shutdown helper on account of
the fact we don't stash the hcd pointer in the driver data, so we provide
our own shutdown handler.

Update the ehci-omap glue layer to support the controller in the
OMAP4. Major differences from OMAP3 is that the OMAP4 has per-port
clocking, and supports ULPI output clocking mode. The old input
clocking mode is not supported.
Also, there are only 2 externally available ports as against 3
in the OMAP3. The third port is internally tied off and should
not be used.

Rename usbhost2_120m_fck to usbhost_hs_fck and usbhost1_48m_fck
to usbhost_fs_fck, to better reflect the clocks' functionalities.
In OMAP4, the frequencies for the corresponding clocks are not
necessarily the same as with OMAP3, however the functionalities
are.

Several of the EHCI glue drivers either predate or were merged in the
same timeframe as API changes at the USB core level, resulting in some
missing endpoint_reset and clear_tt_buffer_complete callbacks.
This fixes up all of ehci-atmel, mxc, w90x900, and xilinx-of to tie in
the new helpers, which brings them in line with everyone else.

Hi,
The [vk][cmz]alloc(_node) family of functions return void pointers which
it's completely unnecessary/pointless to cast to other pointer types since
that happens implicitly.
This patch removes such casts from drivers/usb/

The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus. This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.
The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.
The ehci and ohci blocks share a common clocking and PHY
infrastructure. Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.
Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in
arch/mips/Kconfig in a following patch.

This patch implements the PCI suspend/resume.
Please refer to xHCI spec for doing the suspend/resume operation.
For S3, CSS/SRS in USBCMD is used to save/restore the internal state.
However, an error maybe occurs while restoring the internal state.
In this case, it means that HC internal state is wrong and HC will be
re-initialized.

This commit implements port remote wakeup.
When a port is in U3 state and resume signaling is detected from a device,
the port transitions to the Resume state, and the xHC generates a Port Status
Change Event.
For USB3 port, software write a '0' to the PLS field to complete the resume
signaling. For USB2 port, the resume should be signaling for at least 20ms,
irq handler set a timer for port remote wakeup, and then finishes process in
hub_control GetPortStatus.
Some codes are borrowed from EHCI code.

Do port suspend & resume in terms of xHCI spec.
Port Suspend:
Stop all endpoints via Stop Endpoint Command with Suspend (SP) flag set.
Place individual ports into suspend mode by writing '3' for Port Link State
(PLS) field into PORTSC register. This can only be done when the port is in
Enabled state. When writing, the Port Link State Write Strobe (LWS) bit shall
be set to '1'.
Allocate an xhci_command and stash it in xhci_virt_device to wait completion for
the last Stop Endpoint Command. Use the Suspend bit in TRB to indicate the Stop
Endpoint Command is for port suspend. Based on Sarah's suggestion.
Port Resume:
Write '0' in PLS field, device will transition to running state.
Ring an endpoints' doorbell to restart it.
Ref: USB device remote wake need another patch to implement. For details of
how USB subsystem do power management, please see:

xHCI driver uses hardware assigned device address. This may cause device
address conflict in certain cases.
Use kernel assigned address for devices under xHCI. Store the xHC assigned
address locally in xHCI driver.

Rename xhci_reset_device() to xhci_discover_or_reset_device().
If xhci_discover_or_reset_device() is called to reset a device which does
not exist or does not match the udev, it calls xhci_alloc_dev() to
re-allocate the device.
This would prevent the reset device failure, possibly due to the xHC restore
error during S3/S4 resume.

Add a pointer to udev in struct xhci_virt_device. When allocate a new
virt_device, make the pointer point to the corresponding udev.
Modify xhci_check_args(), check if virt_dev->udev matches the target udev,
to make sure command is issued to the right device.

For all modules, change <module>-objs to <module>-y; remove
if-statements and replace with lists using the kbuild idiom; move
flags to the top of the file; and fix alignment while trying to
maintain the original scheme in each file.
None of the dependencies are modified.

The hardware can only do DMA to 4 byte aligned addresses.
When this requirement is not met use PIO or a bounce buffer.
PIO is used when the buffer is small enough to directly
use the hardware data memory (2*maxpacket).
A bounce buffer is used for larger transfers.

Release the hardware resources and reset the internal HCD state
associated with an isochronous endpoint when the last URB queued
for it completes.
Previously this was only done in then endpoint_disable() method
causing usbtest 15 and 16 to hang when run twice in succession
without a disconnect.

We already have fields describing the hardware data memory
(dmem_size and dmem_offset) in the HCD private data,
use them rather than the rather obscure read from the
hardware descriptor.

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.
