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.
