This patch adds a document describing common OF bindings for video capture, output and video processing devices. It is curently mainly focused on video capture devices, with data busses defined by standards such as ITU-R BT.656 or MIPI-CSI2. It also documents a method of describing data links between devices.

Loading the cypress firmware is not dvb specific and should be common functionality. Move the source to media/common and make it a standalone module. As a result we can remove the dependency on dvb-usb in go7007, which has nothing to do with dvb. Signed-off-by:

vidioc_s_tuner, vidioc_s_frequency and vidioc_s_register now uses a constant argument.

This patch adds all necessary header files and Kbuild plumbing for the core driver for Silicon Laboratories Si476x series of AM/FM tuner chips. The driver as a whole is implemented as an MFD device and this patch adds a core portion of it that provides all the necessary functionality to the two other drivers that represent radio and audio codec subsystems of the chip.

On powerpc the maximum size for the ioctl argument is 8191, and it was 8192. However, the 64x64 array of threshold values is more than is actually needed in practice for PAL and NTSC formats. A 45x45 array will do just fine. So change the size accordingly to fix this problem. Signed-off-by:

Patch protects from setting up frequency on device to incorrect value moving clamp_t check inside amradio_set_freq. With this patch we can call amradio_set_freq() with out of range frequency from any place. Also put comment that sometimes radio->curfreq is set to out of range value in vidioc_s_hw_freq_seek().

This sensor is used by the "SpeedLink Vicious And Devine Laplace webcam" and others. It supports resolutions up to 1600x1200 (at 7-8 fps), but for resolutions higher than 640x480, further driver changes will be necessary, such as sensor output resolution switching (including further configuration changes), bridge xclk adjustment and disabling of 16 bit (12 bit) output formats at high resolutions. Image quality should also needs to be improved. Signed-off-by:

The Windows driver also probes at least two further i2c addresses (0x22 >> 1 and 0x66 >> 1). I've got some hints that they are very likely used by Samsung and Kodak sensors, which are known to be used in Empia devices, too. We havn't seen any devices using these sensors yet and don't know how to probe them properly, so leave a comment. Signed-off-by:

OmniVision sensors are used as well in Empiatech based cameras such as the "SpeedLink Vicious And Devine Laplace" webcam (EM2765 + Omnivision OV2640). With this patch applied, OminiVision sensors with 8 bit address and register width are detected (recent models have a 16 bit address width and use different client addresses). The most commonly used sensors (including the ones listed by Empiatech) are detected properly, although there is no support for them yet. Signed-off-by:

Sensor detection and initialization/configuration are currently mixed together. This works as long as all devices with a particular sensor are working with the same board configuration. In the long run, this will be not sufficient, so separate these both steps to make the code more flexible and future proof. This also makes the code more consistent, because the initialization of the MT9V011 sensor subdevice is already separated. Signed-off-by:

The current board hint code is mixed together with the sensor detection and initialization code. It actually selects a board depending on the detected sensor type only, with the result that 3 of the 6 webcam boards are currently dead. Separate it and move it to em28xx_hint_board() which already contains the board hints for analog capturing+TV and DVB devices. This way, we have all board hints at a common place which makes it easier to extend the code and reduces the risk of regressions. It also makes it possible again to use the boards EM2750_BOARD_DLCW_130, EM2820_BOARD_VIDEOLOGY_20K14XUSB and EM2860_BOARD_NETGMBH_CAM (using the module parameter "card"). NOTE: the current board hint logic for webcams is preserved. Not more not less. Signed-off-by:

Some devices without DVB support (such as the "Terratec Grabby" and "Easycap DC-60") provide isochronous DVB USB endpoints with wMaxPacketSize set to 0 bytes for all alt settings. Ignore these endpoints and avoid registering a DVB device node and loading the DVB driver extension. Signed-off-by:

Streaming doesn't work with the EM2765 if bit 5 of the output format register 0x27 is set. It's actually not clear if really has to be set for the other chips, but for now let's keep it to avoid regressions and add a comment to the code. Signed-off-by:

The webcam "SpeedLink VAD Laplace" (em2765 + ov2640) uses a special algorithm for i2c communication with the sensor, which is connected to a second i2c bus. We don't know yet how to find out which devices support/use it. It's very likely used by all em25xx and em276x+ bridges. Tests with other em28xx chips (em2820, em2882/em2883) show, that this algorithm always succeeds there although no slave device is connected. The algorithm likely also works for real i2c client devices (OV2640 uses SCCB), because the Windows driver seems to use it for probing Samsung and Kodak sensors. Signed-off-by:
