* usb: fix null deferences in low level usb serialJason Wessel2008-09-08
| | | | | | | | | | The hw interface drivers for the usb serial devices deference the tty structure to set up the parameters for the initial console. The tty structure should be passed as a parameter to the set_termios() call.

* USB: automatically enable RHSC interruptsAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | This patch (as1069c) changes the way OHCI root-hub status-change interrupts are enabled. Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

* USB: Don't rebind before "complete" callbackAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | | | | | This patch (as1130) fixes an incompatibility between the new PM infrastructure and USB power management. We are not allowed to call drivers' probe routines during a system sleep transition between the "prepare" and "complete" callbacks, but that's exactly what we do when a driver doesn't have full suspend/resume support. Such drivers are unbound during the "suspend" call and reprobed during the "resume" call. The patch causes the reprobe step to be skipped if the "complete" callback hasn't been issued yet, i.e., if the interface's dev.power.status field is not equal to DPM_ON. Thus during the "resume" callback nothing bad will happen, and during the final "complete" callback the reprobing will occur as desired. This fixes the problem reported in Bugzilla #11263.

* USB: Add new PM callback methods for USBAlan Stern2008-08-21
| | | | | | | | | | | | | | | | This patch (as1129) adds support for the new PM callbacks to usbcore. The new callbacks merely invoke the same old USB power management routines as the old ones did. A minor improvement is that the callbacks are present only in the "USB-device" device_type structure, rather than in the bus_type structure. This way they will be invoked only for USB devices, not for USB interfaces. The core USB PM routines automatically handle suspending and resuming interfaces along with their devices.

* USB: Defer Set-Interface for suspended devicesAlan Stern2008-08-21
| | | | | | | | | | | | | | | | | | This patch (as1128) fixes one of the problems related to the new PM infrastructure. We are not allowed to register new child devices during the middle of a system sleep transition, but unbinding a USB driver causes the core to automatically install altsetting 0 and thereby create new endpoint pseudo-devices. The patch fixes this problem (and the related problem that installing altsetting 0 will fail if the device is suspended) by deferring the Set-Interface call until some later time when it is legal and can succeed. Possible later times are: when a new driver is being probed for the interface, and when the interface is being resumed.

* USB: Add udev argument to interface suspend/resume functionsAlan Stern2008-08-21
| | | | | | | | | | | | | | This patch (as1127) makes a minor change to the prototypes of the usb_suspend_interface() and usb_resume_interface() routines. Now the usb_device structure is passed as an argument, instead of being computed on-the-fly from the usb_interface argument. It makes the code look simpler, even if it really isn't much different from before. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* MUSB: Fix index register corruption seen with g_ether and Windows hostAnand Gadiyar2008-08-21
| | | | | | | | | | | | | | | | | | | | If Indexed Mode register accesses are enabled, the ep0_rxstate() function calls musb_g_ep0_giveback() before writing to the CSR register. When control returns to this ep0_rxstate, the index register contents are over-written. This causes the CSR register write to fail. Fixed by writing the correct value into the index register before writing to the CSR. This was observed only in ep0_rxstate() with g_ether loaded and the device connected to a MS Windows host PC. Anticipatively fixed ep0_txstate() as well. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Acked-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a mechanism to let the write queue drain naturally before closing the TTY, rather than always losing that data. There is a timeout, so it can't wait too long. Provide missing locking inside acm_wb_is_avail(); it matters more now. Note, this presumes an earlier patch was applied, removing a call to this routine where the lock was held. Slightly improved diagnostics on write URB completion, so we can tell when a write URB gets killed and, if so, how much data it wrote first ... and so that I/O path is normally silent (and can't much change timings).

This patch applies the workaround from the ISP1760 FAQ by using two different banks for PTD and payload data and using a common wait for them. This wait is done by an additional ISP1760 access (whose timing constraints guarantee the 90ns delay).

* | | USB: serial gadget: rx path data loss fixesDavid Brownell2008-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update RX path handling in new serial gadget code to cope better with RX blockage: queue every RX packet until its contents can safely be passed up to the ldisc. Most of the RX path work is now done in the RX tasklet, instead of just the final "push to ldisc" step. This addresses some cases of data loss: - A longstanding serial gadget bug: when tty_insert_flip_string() didn't copy the entire buffer, the rest of the characters were dropped! Now that packet stays queued until the rest of its data is pushed to the ldisc. - Another longstanding issue: in the unlikely case that an RX transfer returns data and also reports a fault, that data is no longer discarded. - In the recently added RX throttling logic: it needs to stop pushing data into the TTY layer, instead of just not submitting new USB read requests. When the TTY is throttled long enough, backpressure will eventually make the OUT endpoint NAK. Also: an #ifdef is removed (no longer necessary); and start switching to a better convention for debug messages (prefix them with tty name).

* | | USB Storage Sierra: TRU-Install feature updateKevin Lloyd2008-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch upgrades the support for the Sierra Wireless TRU-Install feature (i.e. zeroCD) to allow for future support of Linux enabled TRU-Install devices. By default all devices that do not have a Linux enabled TRU-Install device (i.e. the device does not have a Linux package on the virtual CD partition) will be switched into "modem mode." Devices that do contain a Linux package in the TRU-Install virtual CD will be allowed to enumerate as a CD-Rom so that either (a) a user can install the packaged software or (b) a user-space application (e.g. udev) can switch it to modem mode. This patch does allow for manual override by adding a usb-storage module parameter 'swi_tru_install' which can force the modem into either mode regardless of what packages it contains.
