Sync up USB parts of the ohci-omap support in mainline with the OMAP tree. This patch supports another first generation OMAP1 part: not just the OMAP 1510 (and its catalog version, the OMAP 5910), but also OMAP 310. From: Tony Lindgren <tony@atomide.com> Signed-off-by:

When removing the procfs file, I forgot to remove some code that created and removed that file. Here's a patch to fix it. Ideally this patch will be melded into the patch removing the procfs file, don't know if it's possible still. Signed-off-by:

Minor musb_hdrc updates: - so it'll build on DaVinci, given relevant platform updates; * remove support for an un-shipped OTG prototype * rely on gpiolib framework conversion for the I2C GPIOs * the <asm/arch/hdrc_cnf.h> mechanism has been removed - catch comments up to the recent removal of the per-SOC header with the silicon configuration data; - and remove two inappropriate "inline" declarations which just bloat host side code. There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h> changes needed in this driver, catching up to the relocation of most of the include/asm-arm/arch-* contents. Signed-off-by: -

Fixes kernel panic while ISO IN transfer is aborted.Replaced usb_hcd_unlink_urb_from_ep() from musb_giveback() to __musb_giveback() to make sure urb is unlinked before giveback when __musb_giveback() is called from musb_urb_dequeue(). Acquired musb->lock() before usb_hcd_unlink_urb_from_ep() within in enqueue path. Signed-off-by:

For those archs which don't provide read/write friends we provide our own implementation so musb driver won't break compilation. This is temporary fix until a better solution comes from upstream. Idealy, <linux/io.h> would provide those calls if the architecture did not provide them yet. In that case being possible to remove all those stubs from musb_io.h Signed-off-by:

The new composite framework revealed a weakness in the s3c2410_udc driver gadget register function. Instead of checking if speed asked for was USB_LOW_SPEED upon usb_gadget_register() to deny service, it checked only for USB_FULL_SPEED, thus denying service to usb high speed capable gadgets (like g_ether).

Offer a "how much VBUS power to request" configuration option for USB gadgets that aren't using board-specific customization of their gadget or (composite) configuration drivers. Also remove a couple pointless "depends on USB_GADGET" bits from the Kconfig text; booleans inside an "if USB_GADGET" will already have that dependency. Based on a patch from Justin Clacherty.

There is no check if platform code passes in more endpoints (num_eps) than the maximum number of enpoints (MUSB_C_NUM_EPS.) The result is that allocate_instance() happily writes past the end of 'struct musb' corrupting memory. This patch adds a BUG() if the platform code requests more than the max. Signed-off-by:

usbmon registers the notifier chain, takes the bus lock and then goes to scan the existing devices for hooking up. Unfortunately, if usb_mon gets initialized while USB bus discovery is going on, it's possible that usbmon gets a notifier on one cpu (which runs without USB locks), and the scan is going on and also finds the new bus, resulting in a double sysfs registration, which then produces a WARNING.

This patch (as1137) changes the hub_activate() routine, replacing the power-power-up and debounce delays with delayed_work calls. The idea is that on systems where the USB stack is compiled into the kernel rather than built as modules, these delays will no longer block the boot thread. At least 100 ms is saved for each root hub, which can add up to a significant savings in total boot time. Arjan van de Ven was very pleased to see that this shaved 700 ms off his computer's boot time. Since his total boot time is on the order of two seconds, the improvement is considerable.

This patch fix 2 problems about reading periodic file: 1. The "..." after a interrupt qh is missed because buffer pointer is not moved. 2. After setting p.ptr as NULL, its next qh or itd will be omited and can't be stored in debug buffer. Signed-off-by:

This patch is based on the following ideas: 1. Some usb devices (such as usb video class) have endpoints of high interval attribute, so reading "periodic" file need more debug buffer to accommodate the qh or itd schedule information. For example, 4KB buffer is not enough for a single interrupt qh of 2ms period. 2. print a %p need 16 byte buffer on 64-bits arch, but 8 byte on 32-bits arch. Add a extra bonus for 64-bits arch.

This patch (as1134) attempts to improve the way we handle OHCI controllers with broken Root Hub Status Change interrupt support. In these controllers the RHSC interrupt bit essentially never turns off, making RHSC interrupts useless -- they have to remain permanently disabled. Such controllers should still be allowed to turn off their root hubs when no devices are attached. Polling for new connections can continue while the root hub is suspended. The patch implements this feature. (It won't have much effect unless CONFIG_PM is enabled and CONFIG_USB_SUSPEND is disabled, but since the overhead is very small we may as well do it.)

This patch (as1118) addresses a problem with certain USB mass-storage devices. These devices sometimes return less data than asked for and then provide no sense data to explain the problem. Currently usb-storage leaves it up to the SCSI layer to decide how this should be handled, and the SCSI layer interprets the lack of sense data to mean that nothing went wrong. But if we got less data than required then something definitely _did_ go wrong, and we should say so. The patch tells the SCSI layer to retry the command when this sort of thing happens. Retrying may not solve the underlying problem, but it's better than believing that data was transferred when it wasn't. Signed-off-by:

Some of Freescale SoC chips have a QE or CPM co-processor which supports full speed USB. The driver adds device mode support of both QE and CPM USB controller to Linux USB gadget. The driver is tested with MPC8360 and MPC8272, and should work with other models having QE/CPM given minor tweaks. Signed-off-by:

In case of error, the function backlight_device_register returns an ERR pointer, but never returns a NULL pointer. So a NULL test that may come after a call to this function should be strengthened by an IS_ERR test. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match_bad_null_test@ expression x, E; statement S1,S2; @@ x = backlight_device_register(...) ... when != x = E * if (x != NULL) S1 else S2 // </smpl> Signed-off-by:

Add a new mechanism to the composite gadget framework, letting functions deactivate (and reactivate) themselves. Think of it as a refcounted wrapper for the software pullup control. A key example of why to use this mechanism involves functions that require a userspace daemon. Those functions shuld use this new mechanism to prevent the gadget from enumerating until those daemons are activated. Without this mechanism, hosts would see devices that malfunction until the relevant daemons start. Signed-off-by:

[This version fixes a thinko in the r8a66597 driver] This patch let a few discrete USB host controllers drivers (isp116x-hcd, r8a66597-hcd and sl811-hcd) obtain IRQ flags from their IORESOURCE_IRQ resource if configured as such, much like it's been done for the smc91x driver. It spares people writing support for specific boards the burden to configure the interrupt controller independantly, and keeps all IRQ related information in a single resource. HCD that are integrally part of a SoC have been left aside, as there is probably no "wiring" options... Tested on an Xscale PXA-255 based platform with isp116x-hcd. Signed-off-by:

looking at usb_kill_urb() it seems to me that it is unnecessarily lenient. In the use case of disconnect() you never want to use the URB again (for the same device) But leaving urb->reject elevated will make it easier to avoid races between read/write and disconnect. Signed-off-by:
