Hugues Fruchet d533d5010e media: stm32-dcmi: g_/s_selection crop support ... Implements g_/s_selection crop support by using DCMI crop hardware feature. User can first get the maximum supported resolution of the sensor by calling g_selection(V4L2_SEL_TGT_CROP_BOUNDS). Then user call to s_selection(V4L2_SEL_TGT_CROP) will reset sensor to its maximum resolution and crop request is saved for later usage in s_fmt(). Next call to s_fmt() will check if sensor can do frame size request with crop request. If sensor supports only discrete frame sizes, the frame size which is larger than user request is selected in order to be able to match the crop request. Then s_fmt() resolution user request is adjusted to match crop request resolution.
