^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) Description: FPGA region id for compatibility check, e.g. compatibility
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) of the FPGA reconfiguration hardware and image. This value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) is defined or calculated by the layer that is creating the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) FPGA region. This interface returns the compat_id value or
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) just error code -ENOENT in case compat_id is not used.
