No, and the 2X8 formats need to be supported at the CCDC input, as BT.656 mode is not compatible with the bridge. I'd rather support them since doing it the other way might be somewhat confusing to the users. It can be confusing indeed, but it reflects reality :-) It's also how we currently handle the lane shifter. If we incorporate the bridge inside the CCDC, only YUV 2X8 formats will be supported at the CCDC input. Whether to enable the bridge will then be a platform decision and hardcoded in board code instead of being configurable by the user. Couldn't that be an issue ? This would also mean media-ctl users would have to set both sink and source formats rather than just the source format when configuring the format for the link. syn_mode |= ISPCCDC_SYN_MODE_PACK8; else syn_mode = ~ISPCCDC_SYN_MODE_PACK8; -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This will clear the PACK8 bit for the YUYV8_2X8 formats. Those formats are 8 bits wide, shouldn't PACK8 be set to store samples on 8 bits instead of 16 bits ? Is this patch intended to support YUYV8_2X8 sensors in non BT.656 mode with the bridge enabled ? In that case, what would you think about setting the CCDC input format to YUYV8_1X16 instead ? This would better reflect the reality, as the bridge converts YUYV8_2X8 to YUYV8_1X16, and the CCDC is then fed with YUYV8_1X16. [Deepthy Ravi] Yes this is intended for YUYV8_2X8 sensors in non BT.656 with 8 to 16 bit bridge enabled. So the data has to be stored as 16 bits per sample. Thats why PACK8 is cleared . I am not sure about using YUYV8_1X16. syn_mode |= ISPCCDC_SYN_MODE_PACK8; else syn_mode = ~ISPCCDC_SYN_MODE_PACK8; -- Regards, Laurent Pinchart -- Thanks, Deepthy Ravi -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
