| | | | | | | | | | | Just a few fixes for problems found after updating v4l2-compliance to check the frequency band enumeration. Note that the i2c driver doesn't fill in bus_info, but since I can't test that driver I've decided not to fix that.

* [media] shark2: New driver for the Griffin radioSHARK v2 USB radio receiverHans de Goede2012-07-305-0/+944
| | | | | | | | | | | | This driver consists of 2 parts, a generic tea5777 driver and a driver for the Griffin radioSHARK v2 USB radio receiver, which is the only driver using the generic tea5777 for now. This first version only implements FM support, once the the new VIDIOC_ENUM_FREQ_BANDS API is upstream I'll also add AM support.

* [media] radio-si470x: Don't unnecesarily read registers on G_TUNERHans de Goede2012-07-303-7/+16
| | | | | | | | | | | | | | | | | | | | | | Reading registers from the pcear USB dongles with the si470x causes a loud pop (and an alsa buffer overrun). Since most radio apps periodically call G_TUNER to update mono/stereo, signal and afc status this leads to the music . pop . music . pop . music -> not good. On the internet there is an howto for flashing the pcear with a newer firmware from the silabs reference boardto fix this, but: 1) This howto relies on a special version of the driver which allows firmware flashing 2) We should try to avoid the answer to a bug report being upgrade your firmware, if at all possible 3) Windows does not suffer from the pop sounds After a quick look at the driver I found at that the register reads are not necessary at all, as the device gives us the necessary status through usb interrupt packets, and the driver already uses these!

| * [media] snd_tea575x: Make the module using snd_tea575x the fops ownerHans de Goede2012-06-112-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch the owner field of the /dev/radio# device fops was set to the snd-tea575x-tuner module itself. Meaning that the module which was using it could be rmmod-ed while the device is open, and then BAD things happen. I know, as I found out the hard way :) Note that there is no need to also somehow increase the refcount of the snd-tea575x-tuner module itself, since any drivers using it will have symbolic references to it.

* [media] radio-si470x-usb: remove autosuspend, implement suspend/resumeHans Verkuil2012-05-142-80/+70
| | | | | | | | | | | | | | | | | | | | | | The radio-si470x-usb driver supported both autosuspend and it stopped the radio the moment the last user of the radio device closed it. However, that was very confusing since if you play the audio from the device (e.g. through arecord -D ... | aplay) then no sound would play unless you had the radio device open at the same time, even though there is no need to do anything with that node. On the other hand, the actual suspend/resume functions didn't do anything, which would fail if you *did* have the radio node open at that time. So: - remove autosuspend (bad idea in general for USB radio devices) - move the start/stop out of the open/release functions into the resume/suspend functions.

* [media] v4l2-dev: add flag to have the core lock all file operationsHans Verkuil2012-05-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This used to be the default if the lock pointer was set, but now that lock is by default only used for ioctl serialization. Those drivers that already used core locking have this flag set explicitly, except for some drivers where it was obvious that there was no need to serialize any file operations other than ioctl. The drivers that didn't need this flag were: drivers/media/radio/dsbr100.c drivers/media/radio/radio-isa.c drivers/media/radio/radio-keene.c drivers/media/radio/radio-miropcm20.c drivers/media/radio/radio-mr800.c drivers/media/radio/radio-tea5764.c drivers/media/radio/radio-timb.c drivers/media/video/vivi.c sound/i2c/other/tea575x-tuner.c The other drivers that use core locking and where it was not immediately obvious that this flag wasn't needed were changed so that the flag is set together with a comment that that driver needs work to avoid having to set that flag. This will often involve taking the core lock in the fops themselves. Eventually this flag should go and it should not be used in new drivers. There are a few reasons why we want to avoid core locking of non-ioctl fops: in the case of mmap this can lead to a deadlock in rare situations since when mmap is called the mmap_sem is held and it is possible for other parts of the code to take that lock as well (copy_from_user()/copy_to_user() perform a down_read(&mm->mmap_sem) when a page fault occurs). It is very unlikely that that happens since the core lock serializes all fops, but the kernel warns about it if lock validation is turned on. For poll it is also undesirable to take the core lock as that can introduce increased latency. The same is true for read/write. While it was possible to make flags or something to turn on/off taking the core lock for each file operation, in practice it is much simpler to just not take it at all except for ioctl and leave it to the driver to take the lock. There are only a handful fops compared to the zillion ioctls we have. I also wanted to make it obvious which drivers still take the lock for all fops, so that's why I chose to have drivers set it explicitly.

* [media] radio-mr800: cleanup and have it comply to the V4L2 APIHans Verkuil2012-05-071-228/+112
| | | | | | | | | | Implement the control framework and update to the latest V4L2 framework. The v4l2-compliance tool now runs without errors. Fixed bad g/s_tuner handling with respect to mono/stereo. Support control events. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] radio-isa: fix memory leakHans Verkuil2012-05-071-5/+3
| | | | | | | | If there is an error when creating controls the v4l2_ctrl_handler_free function must be called. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] dsbr100: clean up and update to the latest v4l2 frameworkHans Verkuil2012-05-041-362/+165
| | | | | | | | | | This driver now complies with the v4l2-compliance tests and uses the v4l2 frameworks correctly. It has been tested with the radio-keene FM transmitter as well. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] V4L: fix incorrect refcountingHans Verkuil2012-04-192-2/+0
| | | | | | | | | | Both radio-keene and dsbr100 did one v4l2_device_get too many. Thus the refcount never became 0 and that causes a memory leak. Also updated the V4L2 framework documentation accordingly. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
