| | | | | | | | | | | | | | | | | | | | | | | | | | | If the camera was set to output formats like RGB565 YUYV or SBGGR10, the resulting image was scrambled due to erroneous interpretations of horizontal parameter's units. This patch in fourcc_to_ipu_pix, eliminate also the pixel formats mappings that, first are not used within mainline code and second, standing at the datasheets, they will not work properly: The IPU internal bus support only the following data formatting (44.1.1.3 Data Flows and Formats): 1 YUV 4:4:4 or RGB-8 bits per color component 2 YUV 4:4:4 or RGB-10 bits per color component 3 Generic data (from sensor to the system memory only) And format conversions are done: - from memory: unpacking from other formats to IPU supported ones - to memory: packing in the inverse order. So, assigning a packing/unpacking strategy to the IPU for those formats will produce a packing to memory and not the inverse.
