Hi all, In the OMAP ISP driver, I'm interested in being able to choose between 8-bit and 12-bit formats when I have a 12-bit sensor attached. At the moment it looks like it's only possible to define this statically with data_lane_shift in the board definition. But with the ISP's lane shifter, it should be possible for the application to ask for 8-bits although it has a 12-bit sensor attached. Has anybody already begun implementing this functionality? One approach that comes to mind is to create a subdev for the bridge/lane shifter in front of the CCDC, but this also seems a bit overkill. Otherwise, perhaps consider the lane shifter a part of the CCDC and put the code in there? Then ccdc_try_format() would have to check whether the sink pad has a pixel format which is shiftable to the requested pixel format on the source pad. A problem with this might be if there are architectures which have a CCDC but no shifter. Are there other approaches I'm not considering? Or problems I'm overlooking? Also- it looks like the CCDC now supports writing 12-bit bayer data to memory. Is that true? thanks for your thoughts, Michael MATRIX VISION GmbH, Talstrasse 16, DE-71570 Oppenweiler Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschaeftsfuehrer: Gerhard Thullner, Werner Armingeon, Uwe Furtner -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
