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.

If you say yes here you get support for the Philips ISP1301
|
|
USB-On-The-Go transceiver working with the OMAP OTG controller.
|
|
The ISP1301 is a full speed USB transceiver which is used in
|
|
products including H2, H3, and H4 development boards for Texas
|
|
Instruments OMAP processors.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called isp1301_omap.

Say Y here if you want to build Intel Langwell USB OTG
|
|
transciever driver in kernel. This driver implements role
|
|
switch between EHCI host driver and Langwell USB OTG
|
|
client driver.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called langwell_otg.
