2010-03-02USB: serial: Remove unnecessary \n's from dbg usesJoe Perches
#define dbg adds the newline, messages shouldn't. Converted dbg("%s", "some string") to dbg("some string") Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-02USB: ehci-dbgp: split PID register updates for IN and OUT pipesJason Wessel
This patch addresses two problems: 1) Bulk reads should always use the DATA0 for the pid, and the write PID should toggle between DATA0 and DATA1. The fix is using dbgp_pid_write_update() and dbgp_pid_read_update(). 2) The delay loop for waiting for a transaction was not long enough to always complete the initial handshake inside dbgp_wait_until_done(). After the initial handshake the maximum delay length is never reached. The combined result of these two changes allows for the removal of the forced resynchronization where a bulk write was issued with a dummy data payload only to get the device to start accepting data writes again.

2010-03-02USB: serial: Add support for ViVOtech ViVOpay devices.Forest Bond
Add support for USB serial interface provided by ViVOtech ViVOpay devices via new driver vivopay-serial. Currently only the ViVOpay 8800 device is supported, but support for similar devices can be added by adding the appropriate device IDs to the driver.

2010-03-02USB: atmel uaba: Adding invert vbus_pinEirik Aanonsen
Adding vbus_pin_inverted so that the usb detect pin can be active high or low depending on HW implementation also replaced the gpio_get_value(udc->vbus_pin); with a call to vbus_is_present(udc); This allows the driver to be loaded and save about 0,15W on the consumption.

2010-03-02USB: Remove unsupported usb gadget driversChristoph Egger
A bunch of USB gadget drivers where never ported from the linux 2.4 series to 2.6 kernels. However there's some code still in the tree for them which isn't used and is probably untested for ages. As the chance of these drivers being forward ported is probably quite small now it might be time to get rid of them.

2010-03-02USB: isp1760: Flush the D-cache for the pipe-in transfer buffersCatalin Marinas
When the HDC driver writes the data to the transfer buffers it pollutes the D-cache (unlike DMA drivers where the device writes the data). If the corresponding pages get mapped into user space, there are no additional cache flushing operations performed and this causes random user space faults on architectures with separate I and D caches (Harvard) or those with aliasing D-cache.

2010-03-02USB: g_mass_storage: superfluous and missing packets fixedMichal Nazarewicz
The mass storage function responded needlessly to a set configuration packet. This was a leftover from converting gadget (file storage gadget) into a composite function.

2010-03-02USB: mass_storage: eject LUNs on thread exitMichal Nazarewicz
Adds a fallback which forces all LUNs ejection (including non-removable and with prevent_medium_removal flag) when mass storage function (MSF) worker thread exits and gadget fails to handle the situation. Previously, if thread_exits was not specified mass storage function (MSF) did nothing when exiting thread as it's unclear for *function* what to do when it's thread terminates so responsibility of handling this situation was left to the *gadget* using the function. The g_mass_storage handled the situation by unregistering itself (the same thing that file storage gadget does). However, g_multi did nothing and so MSF did not eject LUNs which prevented file system unmounting.

2010-03-02USB: pxa27x_udc: Fix deadlocks on request queueingRobert Jarzmik
As reported by Antonio, there are cases where the ep->lock can be taken twice, triggering a deadlock. The typical sequence is : irq_handler \ -> gadget.complete() \ -> pxa27x_udc.pxa_ep_queue() : ep->lock is taken \ -> gadget.complete() \ -> pxa27x_udc.pxa_ep_queue() : ep->lock is taken ==> *deadlock* The patch fixes this by : - releasing the lock each time gadget.complete() is called - adding a check in handle_ep() to detect a recursive call, in which case the function becomes on no-op. The patch is still not good enough for ep0. For this unique endpoint, another well thought over patch will be needed.

2010-03-02USB: serial: add support for serial port on the moschip 7715Mike Dunn
Add support for the serial port on devices based on the MosChip 7715, which provides a serial and parallel port on a single usb interface. This is added to the existing driver for the Moschip 7720 dual serial port device. The 7715 is very similiar to the 7720, requiring only the addition of a calc_num_ports() function, a separate interrupt-in endpoint callback, and some manipulation of the port pointers added to the attach() function to correct the fact that the usbserial core erroneously assigns the first bulk in/out endpoint pair to the serial port (the 7715 uses these for its parallel port). There is no support for the 7715's parallel port yet. Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-02USB: io_edgeport: eliminate get_string()Dan Carpenter
Johan Hovold points out that get_string() is basically just a re-implimentation of usb_string(). It is also buggy. It does DMA on the stack and it doesn't handle negative returns from usb_get_descriptor(). Plus unicode_to_ascii() is a rubbish function and moving to usb_string() avoids using it. Let's eliminate get_string() entirely.
