2011-08-12usb: gadget: hid: don't STALL when processing a HID Descriptor requestSebastian Bauer1-0/+7
This is a patch to fix an issue with the HID gadget which, at the moment, returns STALL on a HID descriptor request. Essentially, the patch changes the hid gadget such that a request for the HID descriptor is handled by copying the descriptor into the response buffer, rather than falling through the default case, in which the request is answered by a STALL.

2011-07-28[media] v4l2-event/ctrls/fh: allocate events per fh and per type instead of ↵Hans Verkuil1-11/+1
just per-fh The driver had to decide how many events to allocate when the v4l2_fh struct was created. It was possible to add more events afterwards, but there was no way to ensure that you wouldn't miss important events if the event queue would fill up for that filehandle. In addition, once there were no more free events, any new events were simply dropped on the floor. For the control event in particular this made life very difficult since control status/value changes could just be missed if the number of allocated events and the speed at which the application read events was too low to keep up with the number of generated events. The application would have no idea what the latest state was for a control since it could have missed the latest control change. So this patch makes some major changes in how events are allocated. Instead of allocating events per-filehandle they are now allocated when subscribing an event. So for that particular event type N events (determined by the driver) are allocated. Those events are reserved for that particular event type. This ensures that you will not miss events for a particular type altogether. In addition, if there are N events in use and a new event is raised, then the oldest event is dropped and the new one is added. So the latest event is always available. This can be further improved by adding the ability to merge the state of two events together, ensuring that no data is lost at all. This will be added in the next patch. This also makes it possible to allow the user to determine the number of events that will be allocated. This is not implemented at the moment, but would be trivial.

2011-07-28[media] v4l2-events/fh: merge v4l2_events into v4l2_fhHans Verkuil1-8/+2
Drivers that supported events used to be rare, but now that controls can also raise events this will become much more common since almost all drivers have controls. This means that keeping struct v4l2_events as a separate struct make no more sense. Merging it into struct v4l2_fh simplifies things substantially as it is now an integral part of the filehandle struct.

2011-07-21fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik1-1/+4
Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

2011-07-08usb: gadget: r8a66597-udc: Make BUSWAIT configurable through platform dataYoshihiro Shimoda1-1/+5
BUSWAIT is a 4-bit-wide value that controls the number of access waits from the CPU to on-chip USB module. b'0000 inserts 0 wait (2 access cycles) and b'1111 inserts 15 waits (17 access cycles, hardware initial value), respectively. BUSWAIT value depends on peripheral clock frequency supplied to on-chip of each CPU, hence should be configurable through platform data. Note that this patch assumes that b'0000 (0 wait, 2 access cycles) is rerely used and considered as invalid. If valid 'buswait' data is not provided by platform, initial b'1111 (15 waits, 17 access cycles) will be applied as a safe default.

There is no reason to continue without data and performing ops on an invalid pointer. - The if (d) statement is bogus since an invalid DMA pointer is ~0 on some architecutres.

2011-07-05usb: gadget: fusb300_udc: drop dead codeFelipe Balbi1-68/+1
that code has been dead forever. Since the first commit (0fe6f1d1) the use of that code has been commented out. Let's drop the dead code already and fix the following compile warning: | drivers/usb/gadget/fusb300_udc.c: At top level: | drivers/usb/gadget/fusb300_udc.c:771:13: warning: ‘fusb300_wrfifo’ defined but not used [-Wunused-function] | drivers/usb/gadget/fusb300_udc.c:1027:13: warning: ‘fusb300_set_ep_bycnt’ defined but not used [-Wunused-function] Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-07-02USB: s3c2410_udc: fix custom UDC command handlingViliam Mateicka1-1/+1
There is a bug in Samsung's UDC driver, which is completely disabling the USB device when a custom UDC command is used. Following patch seems to get the right behavior (e.g. enabling pull-up instead of disabling then Vcc is applied).

2011-07-02USB: gadget: fix req length in sourcesink_setup()Bob Liu1-0/+2
The recent commit 2edb11cbac fixed req->length in the composite_setup() function, but that will cause all g_zero tests to fail like: root#> ./testusb -D /proc/bus/usb/002/021 -t14 -c 15000 -s 256 -v 1 unknown speed /proc/bus/usb/002/021 /proc/bus/usb/002/021 test 14 --> 32 (Broken pipe) We need to fix req->length in sourcesink_setup() as well to avoid this.

2011-07-02usb: gadget: udc-core: add "new-style" registration interfaceSebastian Andrzej Siewior1-4/+71
udc_start() should only trigger the internal state machine and make minimal house keeping. Before that call udc-core calls the bind() callback and after the callback the pullup(). udc_stop() is simillar, udc-core calls pullup(), unbind() and finally udc_stop().
