0807c500a1 USB: add Freescale USB OTG Transceiver driver
Slightly reworked and cleaned up driver from Freescale LTIB
for MPC5121E. The driver has been ported to the current kernel,
proc interface "/proc/driver/fsl_usb2_otg" has been replaced by
sysfs interface.

dfb2130c45 USB: Rename "msm72k_otg.c" to "msm_otg.c"
This driver is used across all MSM SoCs.  Hence give a generic name.
All Functions and strutures are also using "msm_otg" as prefix.

e0c201f339 USB: Add MSM OTG Controller driver
This driver implements PHY initialization, clock management, ULPI IO ops
and simple OTG state machine to kick host/peripheral based on Id/VBUS
line status.  VBUS/Id lines are tied to a reference voltage on some boards.
Hence provide debugfs interface to select host/peripheral mode.

maintain the original scheme in each file.

None of the dependencies are modified.

f0ae849df1 usb: Add Intel Langwell USB OTG Transceiver Driver
This adds support for the USB transceiver driver in the Langwell chipset used
on the Intel MID platforms. It folds up the original patch set which includes
basic support for the device, PHY low power mode (Please notice that there is
a limitation, after we drive VBus down, 2ms delay is required from SCU FW to
sync up OTGSC register with USBCFG register), software timers (the hardware
timers do not work in low power mode), HNP, SRP.

2d57a95f09 USB OTG: Add generic driver for ULPI OTG transceiver
This adds a minimal generic driver for ULPI connected transceivers,
using the OTG framework functions recently introduced.

The driver got a table to match the ULPI chips, which currently only has
one entry for NXP's ISP 1504 transceiver.

1a74826fa1 Revert "USB: Add Intel Langwell USB OTG Transceiver Drive"
This reverts commit 453f775588.

The driver should not have been accepted as the MSRT code is not
in the main kernel yet, which this depends on.

453f775588 USB: Add Intel Langwell USB OTG Transceiver Drive
Description:
This driver is used for Intel Langwell* USB OTG controller in Intel
Moorestown* platform. It tries to implement host/device role switch
according to OTG spec.  The actual hsot and device functions are
accomplished in modified EHCI driver and Intel Langwell USB OTG client
controller driver.

* Langwell and Moorestown are names used in development. They are not
  approved official name.

Note:
This patch is the first version Intel Langwell USB OTG Transceiver
driver. The development is not finished, and the bug fixing is on going
for some hardware and software issues. The main purpose of this
submission is for code view.

Supported features:
- Data-line Pulsing SRP
- Support HNP to switch roles
- PCI D0/D3 power management support

Known issues:
- HNP is only tested with another Moorestown platform.
- PCI D0/D3 power management support is not fully tested.
- VBus Pulsing SRP is not support in current version.

f6d92a05c8 USB: otg: adding nop usb transceiver
NOP transceiver is used by all the usb transceiver which are mostly
autonomous and doesn't require any programming or which are built
into the usb ip itself.NOP transceiver only allocates the memory
for struct xceiv and calls otg_set_transceiver() so function call
to otg_get_transceiver() will return a valid transceiver.

NOP transceiver device should be registered by calling
usb_nop_xceiv_register() from platform files.

9ebd961664 USB: otg: twl4030 transceiver driver
Add driver for the high speed USB-OTG transceiver in TI's TWL4030
family of chips.

Given this and various other pending patches, OMAP3 hardware like
that from beagleboard.org, gumstix.com (Overo), and openpandora.org
should now have basic USB host and peripheral connectivity with
mainline kernels.  Ditto for less widely-available boards.

6084f1bf0c USB: otg: gpio_vbus transceiver stub
gpio_vbus provides simple GPIO VBUS sensing for peripheral
controllers with an internal transceiver.
Optionally, a second GPIO can be used to control D+ pullup.

It also interfaces with the regulator framework to limit charging
currents when powered via USB. gpio_vbus requests the regulator
supplying "vbus_draw" and can enable/disable it or limit its
current depending on USB state.

b8da8677d4 USB: move isp1301_omap to drivers/usb/otg
This moves the isp1301-omap driver from the drivers/i2c/chips
directory (which will be shrinking) into a new drivers/usb/otg
directory (which will grow, with more drivers and utilities).

Note that OTG infrastructure needs to be initialized before
either host or peripheral side USB support, and may be needed
before for pure host or pure peripheral configurations.
