* V4L/DVB: V4L: Events: Add backendSakari Ailus2010-05-19
| | | | | | | | | | Add event handling backend to V4L2. The backend handles event subscription and delivery to file handles. Event subscriptions are based on file handle. Events may be delivered to all subscribed file handles on a device independent of where they originate from.

* V4L/DVB: V4L: File handlesSakari Ailus2010-05-19
| | | | | | | | | | | This patch adds a list of v4l2_fh structures to every video_device. It allows using file handle related information in V4L2. The event interface is one example of such use. The use of v4l2_fh is not mandatory for drivers. Signed-off-by: Sakari Ailus <sakari.ailus@maxwell.research.nokia.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: [v5,2/2] v4l: Add a mem-to-mem videobuf framework test devicePawel Osciak2010-05-19
| | | | | | | | | | | | | | | | This is a virtual device driver for testing the memory-to-memory framework. This virtual device uses in-memory buffers for both its source and destination. It is capable of multi-instance, multi-buffer-per-transaction operation (via the mem2mem framework).

* V4L/DVB: add memory-to-memory device helper framework for videobufPawel Osciak2010-05-19
| | | | | | | | | | | | | | | | | | | | | A mem-to-mem device is a device that uses memory buffers passed by userspace applications for both their source and destination data. This is different from existing drivers, which utilize memory buffers for either input or output, but not both. In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type. Examples of such devices would be: image 'resizers', 'rotators', 'colorspace converters', etc. This patch adds a separate Kconfig sub-menu for mem-to-mem devices as well.

| | | | | | | | | | | Current version of sh_mobile_ceu_camera.c interprets the V4L2 API specification of the VIDIOC_S_CROP ioctl as "change input (for capture devices) area, preserve scaling factors, therefore change output window," whereas a more intuitive interpretation of the API is "change input area, preserve output window."

* V4L/DVB: vivi: clean up and a major overhaulHans Verkuil2010-05-19
| | | | | | | | | | | | | | - Clean up the code - Use the kernel's built-in vga8x16 font instead of our own. - Drop exclusive open: now multiple users can open the device as per the V4L2 spec. - Move the format description to the vivi device instead of keeping it in the file handle. Again as per the spec. - Streamline and simplify the drawing code. It is now easy to add text on top of the colorbar pattern. - Upgrade the max resolution to 1920x1200.

* V4L/DVB: v4l videobuf: add videobuf_buffer *buf as argument to mmap_mapperHans Verkuil2010-05-19
| | | | | | | | | | | | mmap_mapper should operate on a buffer, not on a complete queue. So let the videobuf-core find the correct buffer instead of duplicating that code in each mmap_mapper implementation. The dma-sg implementation has backwards compatibility code for handling the V4L1_COMPAT layer. This code is now under the v4L1_COMPAT config option.

| | | | | | | | | | The video_copy_to_user and copy_stream ops are almost identical for all videobuf memtype variants. All that is needed is to use the new vaddr op and these functions can be moved into the core, ensuring we have just one single implementation instead of three.

* V4L/DVB: Fix default state Beholder H6 tunerDmitri Belimov2010-05-19
| | | | | | | | | | | | | | | | | | The hybrid tuner FMD1216MEX_MK3 after cold start has disabled IF. This tuner has internal I2C switch. This switch switch I2C bus between DVB-T and IF part. Default state is DVB-T. When module saa7134 is load it can't find IF tda9887 and disable analog TV mode. Sets internal I2C switch of the tuner to IF by send special value to the tuner as for receive analog TV from low band. It can be usefule for other cards. I didn't set configure a tuner by a tuner model because this tuner can have different I2C address. May be we can do it later after discuss for more robust support a tuners.
