2010-05-20USB: visor: increase bulk-out buffer sizeJohan Hovold1-0/+3
Increase the bulk-out buffer size to avoid any regression in throughput after replacing the old writing scheme which used dynamic buffers (e.g. up to 2k). 256b has been determined to be a good choice for several drivers including ftdi_sio which used to have a more or less identical write implementation.

2010-05-20USB: EHCI: fix controller wakeup flag settings during suspendAlan Stern5-71/+145
This patch (as1380) fixes a bug in the wakeup settings for EHCI host controllers. When the controller is suspended, if it isn't enabled for remote wakeup then we have to turn off all the port wakeup flags. Disabling PCI PME# isn't good enough, because some systems (Intel) evidently use alternate wakeup signalling paths. In addition, the patch improves the handling of the Intel Moorestown hardware by performing various power-up and power-down delays just once instead of once for each port (i.e., the delays are moved outside of the port loops). This requires extra code, but the total delay time is reduced. There are also a few additional minor cleanups.

2010-05-20USB: ehci-omap: Fix resume failures after bus suspendAnand Gadiyar1-0/+14
An undocumented "feature" in the OMAP3 EHCI controller causes suspended ports to be taken out of suspend when the USBCMD.Run/Stop bit is cleared (this bit is normally cleared when ehci_bus_suspend is called). This "feature" breaks suspend-resume if the root-hub is allowed to suspend. (The controller thinks it is in resume, and the PHY thinks it is still in suspend). There is an undocumented register bit that can be used to disable this feature and restore normal behavior. Set this bit so suspend-resume can work normally. Tested on OMAP3 SDPs with the NXP ISP1504 and NXP ISP1703 PHYs. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
