USB: Add Intel Langwell USB Device Controller driver
Intel Langwell USB Device Controller is a High-Speed USB OTG device controller in Intel Moorestown platform. It can work in OTG device mode with Intel Langwell USB OTG transceiver driver as well as device-only mode. The number of programmable endpoints is different through controller revision. NOTE: This patch is the first version Intel Langwell USB OTG device controller driver. The bug fixing is on going for some hardware and software issues. Intel Langwell USB OTG transceiver driver and EHCI driver patches will be submitted later. Supported features: - USB OTG protocol support with Intel Langwell USB OTG transceiver driver (turn on CONFIG_USB_LANGWELL_OTG) - Support control, bulk, interrupt and isochronous endpoints (isochronous not tested) - PCI D0/D3 power management support - Link Power Management (LPM) support Tested gadget drivers: - g_file_storage - g_ether - g_zero The passed tests: - g_file_storage: USBCV Chapter 9 tests - g_file_storage: USBCV MSC tests - g_file_storage: from/to host files copying - g_ether: ping, ftp and scp files from/to host - Hotplug, with and without hubs Known issues: - g_ether: failed part of USBCV chap9 tests - LPM support not fully tested TODO: - g_ether: pass all USBCV chap9 tests - g_zero: pass usbtest tests - Stress tests on different gadget drivers - On-chip private SRAM caching support Signed-off-by: Xiaochen Shen <xiaochen.shen@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
