It is modelled as Converter (inherited from V4L2M2MConverter) and has a helper to support scaler crop control. The converter acts as a base for now, additional development around dewarping capabilites and support in simple pipeline-handler [1] can be added on top as focused tasks. Patch 1/5 add ability to add features to the Converter interface. Each Converter can dictate its own features it can support Patch 2/5 adds crop feature and gets implemented in the V4L2 M2M converter. Patch 3/5 prepares the rkisp1 pipeline handler to register controls for the camera, outside of the IPA. The ConverterDW100 will let us support scaler crop - which will be registered as one of the camera controls. Patch 4/5 adds a ConverterDW100 class inheriting from converter_v4l2_m2m. This is just a base class for ConverterDW100 with Feature::Crop. Actual dewarp support will extend this class in future. Patch 5/5 plumbs the ConverterDW100 in the rkisp1 pipeline handler Testing: -------- The series is tested on i.MX8MP and cam utility, by setting scaler crop control via capture script with IMX283 attached to isp0. Changes in v5: - Return -ENOTSUP for base implementation for virtual setCrop() in 2/5 - Return configured size for base implemention for virtual getCropBounds in 2/5. - Fix a bug in getting crop bounds when streams are not configured - drop getSelection() V4L2VideoDevices additions from v4. we can get bounds by setSelection by setting 1x1 and UINT_MAX x UINT_MAX rectangles. changes in v4: - rework Converter Interface to expose Features - Add Crop Feature interface in Converter setCrop and setCropBound - Implement cropping in V4L2M2MConverter for V4L2 M2M based converters - Introduce useDewarper_ to denote when to use dewarper (simplied code reading). - Trivial typo fixing. Changes in v3: - Base on top of [2] - Model dewarper class as converter, so can be used with Simple pipeline-handler/ISI Changes in v2: - Fix raw capture configuration, disable dewarper in that case [1]: Supporting the ConverterDW100 is simple pipeline handler should be easy, adding the compatibles string and registering the converter with REGISTER_CONVERTER(). However, for testing the i.MX8MP -> ISI -> ConverterDW100 (dewarper) requires me to have a YUV sensor attached, which I have not abled to source it yet. Once I source it, I will test the ConverterDW100 on simple pipeline handler (I don't expect any issues there but still..) and prepare a integration patch. I hope this doesn't act as blocker for the series.
