2011-02-08USB: ehci: tegra: Align DMA transfers to 32 bytesRobert Morell
The Tegra2 USB controller doesn't properly deal with misaligned DMA buffers, causing corruption. This is especially prevalent with USB network adapters, where skbuff alignment is often in the middle of a 4-byte dword. To avoid this, allocate a temporary buffer for the DMA if the provided buffer isn't sufficiently aligned. Signed-off-by: Robert Morell <rmorell@nvidia.com>

2011-01-09usb: ehci: tegra: remove reschedule rh_timerJay Cheng
Reschedule rh_timer may cause usb device resume fail, as rh_timer may be timeout and send USB_REQ_GET_STATUS SETUP control transfer by the time when the device is handling clear suspend feature, which in turn the device may drop clear suspend feature request. Actually on port resume case, the host driver don't need to reschedule rh_timer to check port status. The host driver will check port status right after suspend feature is cleared.

2010-11-22usb: host: tegra: rewrite usb suspend/resume routine.Jay Cheng
Tegra host controller will time the resume operation to clear the bit when the port control state switches to HS or FS Idle. This behavior is different from EHCI where the host controller driver is required to set this bit to a zero after the resume duration is timed in the driver. Poll PORT_SUSPEND bit till the suspend is completed. Write PORT_RESUME to 0 to clear PORT_SUSPEND bit. Disable disconnect detection during resume.
