Allwinner H3 SoC contains deinterlace unit, which has several modes of operation - bypass, weave, bob and mixed (advanced) mode. I don't know how mixed mode works, but according to Allwinner it gives best results, so they use it exclusively. Currently this mode is also hardcoded here. For each interleaved frame queued, this driver produces 2 deinterlaced frames. Deinterlaced frames are based on 2 consequtive output buffers, except for the first 2, where same output buffer is given to peripheral as current and previous. There is no documentation for this core, so register layout and fixed values were taken from BSP driver. I'm not sure if maximum size of the image unit is capable to process is governed by size of "flag" buffers, frequency or it really is some HW limitation. Currently driver can process full HD image in ~15ms (7.5ms for each capture buffer), which allows to process 1920x1080@60i video smoothly in real time. Acked-by:

Add mean window size parameter for debayer filter as a control in vimc-debayer. vimc-debayer was patched to allow changing mean window parameter of the filter without needing to reload the driver. The parameter can now be set using a v4l2-ctl control(mean_window_size). Co-developed-by:

This also conforms to the media controller doc: 'Most drivers will embed the pads array in a driver-specific structure, avoiding dynamic allocation.' Signed-off-by:

The driver implementation assumed the binning limits could change dynamically based on the binning configuration. This is not actually the case; these limits are static and suitable to be used with all binning configurations but possibly not optimal limit for many of those configurations. Signed-off-by:

The nokia,nvm-size property was used to tell the size of the NVM memory accessible through the sensor's register interface. However, while the size isn't directly readable through the sensor's register interface, it can be detected reading the NVM memory until the selected page is no longer available. Thus remove this property. Signed-off-by:
