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:

If those callbacks fail, it should return zero, and not a random value. The previous code assumed that all drivers would only change signal strength if it succeeds, but this may not be true. Signed-off-by: -
Mauro Carvalho Chehab authored
Now that those functions are only used when the corresponding function calls are defined, we don't need to check if those function calls are present at the structure before using it. Signed-off-by: -

While the driver gets AFC from the tuner, it doesn't return it back via V4L2 API due to a mistake at the return. fix it. Signed-off-by: -
Hans Verkuil authored
If the tuner frontend does not support get_rf_strength, then don't set the has_signal callback. Ditto for get_afc. Both callbacks overwrite the signal and afc fields of struct v4l2_tuner but that should only happen if the tuner can actually detect this. If it can't, then it should leave those fields alone so other subdevices can try and detect the signal/afc. This fixes the bug where the au8522 detected a signal and then tuner-core overwrote it with 0 since the xc5000 tuner does not support get_rf_strength. Signed-off-by:

- open/close/read and poll need to take the core lock as well. - when the tuner goes to sleep we should set std_set_in_tuner_core to 0 since the tuner loses the firmware at that time. - initialize the tuner if std_set_in_tuner_core == 0 whenever: 1) g/s_tuner, s_std or s_frequency is called 2) read or poll is called 3) streamon is called Signed-off-by:

- V4L2_CAP_AUDIO was set, but enumaudio was not implemented. - audioset was never filled by enum_input - ctrl_ainput was never updated when switching the video input - g_audio was broken due to faulty logic: g_audio should set the index, it doesn't receive it from the user. Signed-off-by:

- define an initial frequency - return an error if g_frequency is called for an invalid tuner index - get the clamped frequency value after setting it: i.e. the tuner driver may clamp the given frequency to a valid frequency range and ctrl_freq should get that actual clamped frequency. - remove obsolete tuner type checks (done by the core).

Add support for vidioc_g_chip_name, allowing AC97 to be implemented as a second chip on the bridge with the name "ac97". v4l2-dbg can just match the name with that string in order to detect a ac97-compliant set of registers. Signed-off-by:

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl. This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver. Signed-off-by:

An earlier patch temporarily disabled regional motion detection. This patch adds it back: the 'Motion Detection Enable' control is now a 'Motion Detection Mode'. And to set/get the regional thresholds two new ioctls were added to get/set those thresholds. The BUF_FLAG constants were also updated to prevent clashing with existing buffer flags. Signed-off-by:
