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:

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). [mchehab@redhat.com: use videobuf_queue_to_vaddr instead of the removed videobuf_queue_to_vmalloc] Signed-off-by:

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. Signed-off-by:

AK8814 only differs from AK8813 by included Macrovision Copy Protection function. This patch adds a driver for AK8813 and AK8814 I2C PAL/NTSC TV encoders. Signed-off-by:

A number of SuperH Mobile SoCs, including sh7724, include a Video Output Unit. This patch adds a video (V4L2) output driver for it. The driver uses v4l2-subdev and mediabus APIs to interface to TV encoders. Signed-off-by:

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." Switch sh_mobile_ceu_camera.c to use this interpretation. Signed-off-by:

- 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. Signed-off-by:

drivers/media/video/videobuf-dma-sg.c: In function ‘__videobuf_mmap_mapper’: drivers/media/video/videobuf-dma-sg.c:557: warning: ‘size’ may be used uninitialized in this function The condition where size is floating should never happen, due to the paranoia check, but a future change at the logic might break it. So, let's just set size to zero and use it for the paranoia check. Signed-off-by: -

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. Signed-off-by:

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. Signed-off-by:

Rename the .vmalloc op in struct videobuf_qtype_ops to .vaddr. This op returns the virtual kernel address of a buffer. vaddr is a lot less confusing than vmalloc since this callback does do any allocations. Signed-off-by:

The enum fe_caps provides flags that allow an application to detect whether a device is capable of handling various modulation types etc. A flag for detecting PSK_8, however, is missing. This patch adds the flag FE_CAN_PSK_8 to frontend.h and implements it for the gp8psk-fe.c and cx24116.c driver (apparently the only ones with PSK_8). Only the gp8psk-fe.c has been explicitly tested, though. Signed-off-by:

The imon driver I've previously submitted and have been porting to use ir-core needs to use ir_g_keycode_from_table, as ir_keydown is not sufficient, due to these things having really oddball hardware decoders in them. This just moves the function declaration from ir-core-priv.h over to ir-core.h. Signed-off-by:
