The only two countries that are known to use 6MHz bandwidth are Taiwan and Uruguay. Both use QAM subcarriers at OFTM. This patch fixes the firmware load for such countries, where the required firmware is the QAM one. This also confirms the previous tests where it was noticed that the 6MHz QAM firmware doesn't work for cable. So, this patch also removes support for DVB-C, instead of just printing a warning. Thanks to Terry Wu <terrywu2009@gmail.com> for pointing this issue and to Andy Walls <awalls@radix.net> for an initial patch for this fix. Cc: Terry Wu <terrywu2009@gmail.com> Acked-by:

Thanks to David Ward and Mike Krufky for reporting the problem and debugging this as an unresolved symbol due to a 64 bit divide on a 32 bit system. David Ward provided the content of this patch; Andy Walls only performed some cosmetic edits. Reported-by:

Test Code: (Provided by Douglas) v4l-dvb/v4l2-apps/test/stress-buffer.c The audio DMA area was never being freed and would slowly leak over time as the v4l device was opened and closed by an application. Thanks again to Douglas for generating the test code to help locate memory leaks!!! Signed-off-by:

Fix the burst gate delays to use a crystal value of 28636360 as assumed by the rest of the driver. Also have the initial color sub-carrier freq paramter use the src decimation ratio per the documentation, instead of the actual crystal/pixel clock ratio. The tracking circuit will find the correct color subcarrier in any case, as long as we're close. Also fix up some debug print statements. Signed-off-by:

The i2c quirk in the saa7134_i2c_xfer function does a bogus write to i2c address 0xfd, to work around a bug in the silicon that affects read transactions. Unfortunately, this hack is not working properly, since the bogus write is to 0xfd, an invalid i2c address. Fix this quirk by using an actual valid i2c address, 0xfe, which is still unlikely to be used as an i2c address for any actual i2c client. This is required in order to properly communicate with a TDA10048 DVB-T demod located at i2c address 0x10 on the primary i2c bus. Signed-off-by:

Now that the ir-kbd-i2c driver has been converted to a new-style i2c driver, we can instantiate the ir_video I2C device by default. The pvr2_disable_ir_video is kept to disable the IR receiver, either because the user doesn't use it, or for debugging purpose. Signed-off-by:

The code in ir_probe makes the dangerous assumption that all IR receivers are supported by the driver. The new i2c model makes it possible for bridge drivers to instantiate IR devices before they are supported, therefore the ir-kbd-i2c drivers must be made more robust to not spam the logs or even crash on unsupported IR devices. Simply, the driver will not bind to the unsupported devices. Signed-off-by:

For specific boards, pass initialization data to ir-kbd-i2c instead of modifying the settings after the device is initialized. This is more efficient and easier to read. Signed-off-by:

Let card drivers probe for IR receiver devices and instantiate them if found. Ultimately it would be better if we could stop probing completely, but I suspect this won't be possible for all card types. There's certainly room for cleanups. For example, some drivers are sharing I2C adapter IDs, so they also had to share the list of I2C addresses being probed for an IR receiver. Now that each driver explicitly says which addresses should be probed, maybe some addresses can be dropped from some drivers. Also, the special cases in saa7134-i2c should probably be handled on a per-board basis. This would be more efficient and less risky than always probing extra addresses on all boards. I'll give it a try later. Signed-off-by:

In the standard device driver binding model, the name field of struct i2c_client is used to match devices to their drivers, so we must stop using it for internal purposes. Define a separate field in struct IR_i2c as a replacement, and use it. Signed-off-by:

dvb_dvr_read may unlock the dmxdev mutex and return -ENODEV, except this function is a file op and will never be called with the mutex held. There's existing mutex_lock and mutex_unlock around the actual read but it's commented out. These should probably be uncommented but the read blocks and this could block another non-blocking reader on the mutex instead. This change comments out the extra mutex_unlock.

Change kmalloc()/kfree() to vmalloc()/vfree() for sglist allocation during videobuf_dma_map() and videobuf_dma_unmap() High resolution sensors might require too many contiguous pages to be allocated for sglist by kmalloc() during videobuf_dma_map() (i.e. 256Kib for 8MP sensor). In such situations, kmalloc() could face some problem to find the required free memory. vmalloc() is a safer solution instead, as the allocated memory does not need to be contiguous. Signed-off-by:

Most UVC camera include an interrupt endpoint to report control value changes, video streaming errors and camera button events. The USB controller continuously polls the interrupt endpoint to retrieve such events. This prevents the device from being auto-suspended, and thus consumes power. Reporting video streaming errors don't make sense when the V4L2 device is closed. Control value changes are probably useless as well if nobody listens to the events, although caching will probably have to be completely disabled then. No polling is thus be required when /dev/videoX is not opened. To enable auto-suspend and save power do not poll the interrupt endpoint until the device is open. We lose the ability to detect button events if no application is using the camera. http://bugzilla.kernel.org/show_bug.cgi?id=11948Signed-off-by:
