@thenguyenyf Nice, thanks! Are you able to give a short presentation of this in an Architecture Working Group meeting? |
Hello @henrikbrixandersen . I'm willing to join and give a presentation for the new CRC subsystem. How about next week meeting? I may not be able to join this week. |

This PR is inherited from #74977 to add a CRC device driver with hardware accelerator. We'd like to introduce:
include/zephyr/drivers/crc.hinclude/zephyr/crc_new/crc_new.hThe crc_new subsys implementation can be chosen as:
zephyr,crcalias if it's definedinclude/zephyr/sys/crc.hThe crc_new is an adapter layer with similar function like zephyr/include/zephyr/sys/crc.h, but has a compatible interface to the device driver model to make it work with hardware accelerators. Old libraries that are being used by other software will be retained.
