2008-09-25si470x: removement of get/set input/audioTobias Lorenz
From: Tobias Lorenz <tobias.lorenz@gmx.net> Hi Mauro, this patch removes the unnecessary get/set input/audio functions. The reason is, that the V4L2 specification says, that if input or audio cannot be switched anyway, the functions doesn't need to be implemented. I've tested the new driver with all current radio programs in Debian/testing and found no problems with that. In my opinion, the driver is much cleaner by removing these unnecessary functions.

2008-09-25si470x: correction of mono/stereo handlingTobias Lorenz
From: Tobias Lorenz <tobias.lorenz@gmx.net> Hi Mauro, this patch corrects the behavior of mono/stereo indication and selection. These functions now work conform to what's defined in the V4L2 specification. Bye, Toby Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net>
2008-09-25si470x: tuner->type handlingTobias Lorenz
From: Tobias Lorenz <tobias.lorenz@gmx.net> Hi Mauro, the V4L2 specification says, when to check and when to return tuner->type as constant value. This patch corrects exactly this behavior, so that it is now conform to the V4L2 specification. Bye, Toby Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net>
2008-09-25si470x: improvement of unsupported base controlsTobias Lorenz
From: Tobias Lorenz <tobias.lorenz@gmx.net> Hi Mauro, this patch changes the handling of unsupported base controls. In the former version, specific unsupported base controls were listed in the queryctrl table and were flagged as disabled controls. This was done for all base controls used by the applications. The patch now removes the specific base controls and instead lets queryctrl automatically return unsupported base controls flagged as disabled. Bye, Toby Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net>
2008-09-25si470x: improvement of module device supportTobias Lorenz
From: Tobias Lorenz <tobias.lorenz@gmx.net> Hi Mauro, this patch improves support for multiple radio devices. In previous versions all region relevant settings were derived from one module parameter. As in future versions, the region and other configuration should be configurable per device from the user space, this patch already retrieves all relevant information from the actual device specific settings. Best regards, Toby Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net>
2008-09-25si470x: module_param access rightsTobias Lorenz
From: Tobias Lorenz <tobias.lorenz@gmx.net> Hi Mauro, this patch mainly adds correct module_param access rights. Also there are a lot of small coding style enhancements and some corrections of the variable references in module_param. Best regards, Toby Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net>

2008-10-01radio-mr800: Add driver for AverMedia MR 800 USB FM radio devicesDouglas Schilling Landgraf

This device plugs into both the USB and an analog audio input, so this thing only deals with initialization and frequency setting, the audio data has to be handled by a sound driver.

2008-07-30v4l: move BKL down to the driver level.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.

From: Hans Verkuil <hverkuil@xs4all.nl> All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it. This ensures a clean separation between the const ops struct and the non-const video_device struct.

2008-03-23 radio-si470x: unplugging fixedMauro Carvalho Chehab
From: Tobias Lorenz <tobias.lorenz@gmx.net> this patch fixes several kernel oops, when unplugging device while it is in use: Basically the patch delays freeing of the internal variables in si470x_usb_driver_disconnect, until the the last user closed the device in si470x_fops_release. This was implemented a while ago with the help of Oliver Neukum. I tested the patch five times (unplugging while in use) without oops coming from the radio-si470x driver anymore. A remaining oops was coming from the usbaudio driver, but this is someone else task. Hopefully this fixed all unplugging issues.

2008-02-04 radio-si470x version 1.0.6Mauro Carvalho Chehab
From: Tobias Lorenz <tobias.lorenz@gmx.net> This patch combines all the finished discussions and its resulting patches from the mailing list. The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of small issues, that are fixed with this patch now. For me the most interesting thing is, that it's now safer to use it on other architectures. The history for version 1.0.6 is: - fixed coverity checker warnings in *_usb_driver_disconnect - probe()/open() race by correct ordering in probe() - DMA coherency rules by separate allocation of all buffers - use of endianness macros - abuse of spinlock, replaced by mutex - racy handling of timer in disconnect, replaced by delayed_work - racy interruptible_sleep_on(), replaced with wait_event_interruptible() - handle signals in read() The driver is tested with all Debian/testing radio programs and rdsd.

2008-02-02Fix Kconfig dependenciesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes. This patch moves the functions that videodev needs from v4l2-common. It also fixes some Kconfig changes. After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked into kernel. v4l2-common will be m, and all V4L drivers will also be m. This approach is very conservative, since it is possible to have V4L drivers that don't need I2C or v4l2-common. The better is to map what drivers really need v4l2-common, making them to select v4l2-common, and allowing the others to be 'y', 'm' and 'n'.
