Please look at this page: https://linuxtv.org/wiki/index.php/Development:_How_to_submit_patches#Firmware_submission The information here can also be useful: https://www.kernel.org/doc/readme/firmware-README.AddingFirmware In summary, you need to provide redistribution rights for the firmware blob. You can either submit it to me or directly to linux-firmware. In the latter, please c/c me on such patch. Thanks!
