This patch introduces a compat_id pointer member and sysfs interface for each fpga region, similar as compat_id for fpga manager, it allows applications to read the per region compat_id for compatibility checking before other actions on this fpga-region (e.g. PR).

Description: FPGA region id for compatibility check, e.g. compatibility
|
|
of the FPGA reconfiguration hardware and image. This value
|
|
is defined or calculated by the layer that is creating the
|
|
FPGA region. This interface returns the compat_id value or
|
|
just error code -ENOENT in case compat_id is not used.
