2012-03-01Merge tag 'gadget-for-v3.4' of ↵Greg Kroah-Hartman1-38/+8
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: Gadget: changes for 3.4 This merge is rather big. Here's what it contains: For am5536udc we have just simple coding style fixes. Nothing that has any potential to cause any issues going forward. With mv_udc, there's only one single change removing an unneeded NULL check. at91_udc also only saw a single change this merge window, and that's only removing a duplicated header. The Renesas controller has a few more involved changes. Support for SUDMAC was added, there's now a special handling of IRQ resources for when the IRQ line is shared between Renesas controller and SUDMAC, we also had a bug fix where Renesas controller would sleep in atomic context while doing DMA transfers from a tasklet. There were also a set of minor cleanups. The FSL UDC also had a scheduling in atomic context bug fix, but that's all. Thanks to Sebastian, the dummy_hcd now works better than ever with support for scatterlists and streams. Sebastian also added SuperSpeed descriptors to the serial gadgets. The highlight on this merge is the addition of a generic API for mapping and unmapping usb_requests. This will avoid code duplication on all UDC controllers and also kills all the defines for DMA_ADDR_INVALID which UDC controllers sprinkled around. A few of the UDC controllers were already converted to use this new API. Conflicts: drivers/usb/dwc3/gadget.c

2011-09-18usb: Provide usb_speed_string() functionMichal Nazarewicz1-33/+17
In a few places in the kernel, the code prints a human-readable USB device speed (eg. "high speed"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To mitigate this issue, this commit introduces usb_speed_string() function, which returns a human-readable name of provided speed. It also changes a few places switch was used to use this new function. This changes a bit the way the speed is printed in few instances at the same time standardising it.

2009-06-16USB: Add Intel Langwell USB Device Controller driverXiaochen Shen1-0/+3373
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>
