2013-10-11USB: EHCI: check the right uframes for CSPLITAlan Stern1-1/+1
The check_intr_schedule() routine in ehci-hcd looks at the wrong microframes when checking to see if a full-speed or low-speed interrupt endpoint will fit in the periodic schedule. If the Start-Split transaction is scheduled for microframe N then the Complete-Split transactions get scheduled for microframes N+2, N+3, and N+4. However the code considers N+1, N+2, and N+3 instead. This patch fixes the limits on the "for" loop and also improves the use of whitespace.

2013-10-11usb-anchor: Delay usb_wait_anchor_empty_timeout wake up till completion is doneHans de Goede2-2/+45
usb_wait_anchor_empty_timeout() should wait till the completion handler has run. Both the zd1211rw driver and the uas driver (in its task mgmt) depend on the completion handler having completed when usb_wait_anchor_empty_timeout() returns, as they read state set by the completion handler after an usb_wait_anchor_empty_timeout() call. But __usb_hcd_giveback_urb() calls usb_unanchor_urb before calling the completion handler. This is necessary as the completion handler may re-submit and re-anchor the urb. But this introduces a race where the state these drivers want to read has not been set yet by the completion handler (this race is easily triggered with the uas task mgmt code). I've considered adding an anchor_count to struct urb, which would be incremented on anchor and decremented on unanchor, and then only actually do the anchor / unanchor on 0 -> 1 and 1 -> 0 transtions, combined with moving the unanchor call in hcd_giveback_urb to after calling the completion handler. But this will only work if urb's are only re-anchored to the same anchor as they were anchored to before the completion handler ran. And at least one driver re-anchors to another anchor from the completion handler (rtlwifi). So I have come up with this patch instead, which adds the ability to suspend wakeups of usb_wait_anchor_empty_timeout() waiters to the usb_anchor functionality, and uses this in __usb_hcd_giveback_urb() to delay wake-ups until the completion handler has run.

2013-10-11usb: musb: start musb on the udc side, tooSebastian Andrzej Siewior4-46/+49
I have am335x-evm with one port running in OTG mode. Since commit fe4cb09 ("usb: musb: gadget: remove hcd initialization") the loaded gadget does non pop up on the host. All I see is |usb 4-5: new high-speed USB device number 52 using ehci-pci |usb 4-5: device descriptor read/64, error -110 Since a later commit 2cc65fe ("usb: musb: add musb_host_setup() and musb_host_cleanup()) the gadget shows up on the host again but only in OTG mode (because we have the host init code running). It does not work in device only mode. If running in OTG mode and the gadget is removed and added back (rmmod followed by modprobe of a gadget) then the same error is pops up on the host side. This patch ensures that the gadget side also executes musb_start() which puts the chip in "connect accept" mode. With this change the device works in OTG & device mode and the gadget can be added & removed multiple times. A device (if musb is in OTG mode acting as a host) is only recognized if it is attached during module load (musb_hdrc module). After the device unplugged and plugged again the host does not recognize it. We get a buch of errors if musb running in OTG mode, attached to a host and no gadget is loaded. Bah. This is one step forward. Host & device only mode should work. I will look at OTG later. I looked at this before commit fe4cb09 and OTG wasn't working there perfectly so I am not sure that it is a regression :) Cc: <[email protected]> # v3.11 Cc: Daniel Mack <[email protected]> Cc: Peter Korsgaard <[email protected]> Signed-off-by: Sebastian Andrzej Siewior <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

2013-10-10usb: gadget: f_mass_storage: make sysfs interface optionalAndrzej Pietrasiewicz3-14/+59
When configfs is in place, the luns will not be represented in sysfs, so there will be no struct device associated with a lun. In order to maintain compatibility and allow configfs adoption sysfs is made optional in this patch. As a consequence some debug macros need to be adjusted. Two new fields are added to struct fsg_lun: name and name_pfx. The "name" is for storing a string which is presented to the user instead of the dev_name. The "name_pfx", if non-NULL, is prepended to the "name" at printing time. The name_pfx is for a future lun.0, which will be a default group in mass_storage.<name>. By design at USB function configfs group's creation time its name is not known (but instead set a bit later in drivers/usb/gadget/configfs.c:function_make) and it is this name that serves the purpose of the said name prefix. So instead of copying a yet-unknown string a pointer to it is stored in struct fsg_lun.

Also added check if maxpacket isn't grater than 1024 which is maximum size od single USB transaction.

2013-10-09xhci: Fix spurious wakeups after S5 on HaswellTakashi Iwai3-0/+25
Haswell LynxPoint and LynxPoint-LP with the recent Intel BIOS show mysterious wakeups after shutdown occasionally. After discussing with BIOS engineers, they explained that the new BIOS expects that the wakeup sources are cleared and set to D3 for all wakeup devices when the system is going to sleep or power off, but the current xhci driver doesn't do this properly (partly intentionally). This patch introduces a new quirk, XHCI_SPURIOUS_WAKEUP, for fixing the spurious wakeups at S5 by calling xhci_reset() in the xhci shutdown ops as done in xhci_stop(), and setting the device to PCI D3 at shutdown and remove ops. The PCI D3 call is based on the initial fix patch by Oliver Neukum. [Note: Sarah changed the quirk name from XHCI_HSW_SPURIOUS_WAKEUP to XHCI_SPURIOUS_WAKEUP, since none of the other quirks have system names in them. Sarah also fixed a collision with a quirk submitted around the same time, by changing the xhci->quirks bit from 17 to 18.] This patch should be backported to kernels as old as 3.0, that contain the commit 1c12443ab8eba71a658fae4572147e56d1f84f66 "xhci: Add Lynx Point to list of Intel switchable hosts."

The function pci_write_config_dword() sets the appropriate byteordering internally so the value argument should not be converted to little-endian. This bug was found by sparse. This patch is not suitable for stable.
