Chip id 18 is used by the em2710 and em2820. The current code assumes that if the device is a camera, the chip is an em2710 and an em2820 otherwise. But it turned out that the em2820 is also used in camera devices. "Silvercrest 1.3 MPix" webcams for example are available with both chips. Fortunately both variants are using different generic USD IDs which give us a hint about the used chip. Signed-off-by:

The snapshot button support is currently broken, because module em28xx-rc is loaded only if the device has remote control support. Fix it by also loading this module if the device has a snapshot button. Signed-off-by:

This prepares the driver for priority and control event handling. This patch also checks for correct streaming ownership and it makes a small improvement to the encoder_cmd ioctls: always zero 'flags' and drop the memset of 'raw' as that is already done by the v4l2 core. Signed-off-by:

These formats are supported by the HDPVR, but they were missing in the list. Note that these formats are different from the common PAL/NTSC/SECAM formats since all color channels are transmitted separately and so there is no PAL or NTSC or SECAM color encoding involved. Signed-off-by:

This was set to 1 << 0 which is the same as V4L2_DV_FL_REDUCED_BLANKING. It should be 1 << 3 instead. Luckily interlaced formats are rarely used, which is why this bug wasn't seen until now. Signed-off-by:

Simplify locking by using the V4L2 core lock mechanism. This allows us to remove all locking from the i2c module. This will also simplify the upcoming conversion to the control framework. Signed-off-by:

After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to just MATCH_SUBDEV. The v4l2-dbg utility is much better placed to match by name by just enumerating all bridge and subdev devices until chip_name.name matches. Signed-off-by:

Only enable this ioctl if the VIDEO_ADV_DEBUG config option is set. This prevents abuse from both userspace and kernelspace (some bridge drivers abuse DBG_G_CHIP_IDENT, lets prevent that from happening again with this ioctl). Signed-off-by:

The get_rf_strength op in tuner-simple is valid only for the radio mode. But due to the way get_signal in analog_demod_ops was designed it would overwrite the signal value with a bogus value when in TV mode. Pass a pointer to the signal value instead, and when not in radio mode leave it alone in the tuner-simple. This broke in commit 030755bd (tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before that this was working correctly. That commit did the right thing, but what wasn't realized at the time was that tuner-simple should have been updated as well to restrict setting the signal strength to the radio mode only.

The get_afc op in tda9887 is valid only for the radio mode. But due to the way get_afc in analog_demod_ops was designed it would overwrite the afc value with a bogus value when in TV mode. Pass a pointer to the afc value instead, and when not in radio mode leave it alone in the tda9887. This broke a long time ago in 2.6.19 when the get_afc op was introduced. Before that the afc was only set for radio mode in the tda9887. Signed-off-by:
