usb: otg: kill langwell_otg driver

2012-01-24T13:41:51Z

The way this driver was added by f0ae849 (usb: Add Intel Langwell USB OTG Transceiver Driver) never even compiled together with langwell_udc, and that's the only way for it to be useful.

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.

Revert "USB: Add Intel Langwell USB OTG Transceiver Drive"

2009-07-12T22:16:36Z

This reverts commit 453f77558810ffa669ed5a510a7173ec49def396. The driver should not have been accepted as the MSRT code is not in the main kernel yet, which this depends on. Cc: Alan Cox Cc: Hao Wu Signed-off-by: Greg Kroah-Hartman

USB: Add Intel Langwell USB OTG Transceiver Drive

2009-06-16T04:44:47Z

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.
