The tveeprom module is a helper module for Hauppauge-based eeproms. It's used by many drivers and the i2c part is actually optional, so this driver is better placed in the media/common directory. Signed-off-by:

The btcx-risc module is a helper module for bttv/conexant based TV cards. It isn't an i2c module at all, instead it should be in common since it is used by 4 pci drivers. Signed-off-by:

The cx2341x module is a helper module for conexant-based MPEG encoders. It isn't an i2c module at all, instead it should be in common since it is used by 7 pci and usb drivers to handle the MPEG setup. It also shouldn't be visible in the config menu as it is always selected automatically by those drivers that need it. Signed-off-by:

The ttusb2 module is already updated to recognize the TechnoTrend CT-3650 CI DVB C/T USB2.0 receiver in addition to the Pinnacle 400e. But if MEDIA_SUBDRV_AUTOSELECT is used, the required tuner and demodulator modules are not automatically selected. Here's a patch to fix that and add a note of the CT-3650 to the online help of the ttusb2 module. This patch applies cleanly to 3.7.6 and other 3.7.x kernels. Signed-off-by: -

This patch move the soft reset to the attach function because with dual tuners, when one tuner do reset, the other one is perturbed, and the stream has errors. Signed-off-by:

This patch adds new capture board Hawell HW-9004V1. This card has 4 SAA71300 chips. In order to work it is needed to initialize its registers (gpio mask and value). The value of these registers were dumped under Windows using flytest. Signed-off-by:

This allocation had no error checking. It didn't need to be under the mutex so I moved it out form there. That makes the error handling easier and is a potential speed up. Signed-off-by:

via-camera and mcam-core were the only bridge drivers that used ov7670. Since now they have been moved to use the ctrl framework, the old legacy callbacks in the ov7670 can be removed. Signed-off-by:

Some bridge drivers capture pixels during blanking periods if pixclk is enabled. In order to avoid capturing bogus data we need to disable pixclk in the sensor during those blanking periods. Acked-by:

For a frame rate of 30 fps a pixclk of 24MHz is needed. For those cases where the ov7670 has a clean 24MHz input (xvclk) the PLL can be bypassed. This will result in a value of clkrc of 1, which means that in practice pixclk = xvclk (input clock) Acked-by:

According to the datasheet ov7675 uses a formula to achieve the desired framerate that is different from the operations done in the current code. In fact, this formula should apply to ov7670 too. This would mean that current code is wrong but, in order to preserve compatibility, the new formula will be used for ov7675 only. Signed-off-by:

'min_height' and 'min_width' are variables that allow to specify the minimum resolution that the sensor will achieve. This patch make v4l2 fmt callbacks consider this parameters in order to return valid data to user space. Acked-by:

Javier Martin authored
ov7675 and ov7670 share the same registers but there is no way to distinguish them at runtime. However, they require different tweaks to achieve the desired resolution. For this reason this patch adds a new ov7675 entry to the ov7670_id table. Signed-off-by:

- move the bit shifting of width+height values inside the function - fix the debug message format and output values - add comment about the size limit (e.g. EM277x supports >2MPix) - make void, because error checking is incomplete and we never check the returned value (we would continue anyway) Signed-off-by:

All drivers which use this subdevice use also the control framework. The v4l2_subdev_core_ops operations {query/g_/s_}ctrl are useless because device drivers will inherit controls from this subdevice. Signed-off-by:Federico Vaga <federico.vaga@gmail.com> Signed-off-by:

This patch re-write the driver and use the videobuf2 interface instead of the old videobuf. Moreover, it uses also the control framework which allows the driver to inherit controls from its subdevice (ADV7180). Finally the driver does not implement custom file operation but it uses the generic ones from videobuf2 and v4l2_fh Signed-off-by:

The buffer ioctls (VIDIOC_REQBUFS, VIDIOC_QUERYBUF, VIDIOC_QBUF, VIDIOC_DQBUF, VIDIOC_EXPBUF, VIDIOC_CREATE_BUFS, VIDIOC_PREPARE_BUF) are not applicable for radio devices. Hence, they should be set valid only for non-radio devices in determine_valid_ioctls(). Signed-off-by:

Clear the proper array when deregistering FIMC-LITE devices. Now fimc[] array is erroneously accessed instead of fimc_lite[] and fimc_md_unregister_entities() function call can result in an oops from NULL pointer dereference, since fmd->fimc[] is cleared earlier. This might happen in normal conditions when the driver's probing is deferred and then retried. Signed-off-by:
