Kill custom read and write implementations (static 16*4k write-urb pool shared among all ports in system). Also remove old changelog entries in header (code is now gone, and these entries can still be retrieved through git). Compile-only tested. Signed-off-by:

This patch adds support for an olivetti olicard100 HЅDPA usb-stick. This device is a zeroCD one with ID 0b3c:c700 that needs switching via eject or usb-modeswitch with MessageContent="5553424312345678000000000000061b000000030000000000000000000000". After switching it has ID 0b3c:c000 and provides 5 serial ports ttyUSB[0-4]. Port 0 (modem) and 4 are interrupt ports. Signed-off-by:

Since commit 7acd72eb ("kfifo: rename kfifo_put... into kfifo_in... and kfifo_get... into kfifo_out..."), kfifo_out() is marked __must_check, and that causes gcc to produce lots of warnings like this: CC drivers/usb/host/fhci-mem.o In file included from drivers/usb/host/fhci-hcd.c:34: drivers/usb/host/fhci.h: In function 'cq_get': drivers/usb/host/fhci.h:520: warning: ignoring return value of 'kfifo_out', declared with attribute warn_unused_result ...

Use kzalloc rather than the combination of kmalloc and memset. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // </smpl> Signed-off-by:

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. Signed-off-by:

In to places in fsg_common_init() an unconditional call to kfree() on common was performed in error recovery which is not a valid behaviour since fsg_common structure is not always allocated by fsg_common_init(). To fix, the calls has been replaced with a goto to a proper error recovery which does the correct thing. Also, refactored fsg_common_release() function. Signed-off-by:

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:

This patch (as1379) reworks the logic for handling USB interface runtime-PM settings -- hopefully it's right this time! The problem is that when a driver is unbound or binding fails, runtime PM for the interface always gets disabled. But pm_runtime_disable() nests, so it shouldn't be called unless the interface was previously enabled for runtime PM. Signed-off-by:

On OMAP systems, we have two different OHCI controllers. The legacy one is present in OMAP1/2 chips, and the newer one comes bundled as a companion to the EHCI controller on OMAP3 and newer chips. We may have multi-omap configurations where OMAP2 and OMAP3 support may be enabled in the same kernel, and need a mechanism to keep both drivers around. This patch adds a Kconfig entry for each of these drivers. Signed-off-by:
