Marjor changes against v4 are sysfs related code rework to address comments on v4. Please help to take a look. Thanks! Main changes from v4: - convert code to use dev_groups for sysfs entries (#2, #3, #4, #6, #8). - clean up for empty init function after remove sysfs add/remove (#1). - introduce is_visible for sysfs groups (#3, #4, #6, #8). - remove revision sysfs entries (#4, #6, #8). - improve naming on shared functions (#5). - reorganize sysfs entries for port and fme error reporting (#6, #8). Main changes from v3: - drop avx512 partail reconfiguration patch for now. - split dfl_fpga_cdev_config_port to 2 functions *_release/assign_port (#1). - split __dfl_fpga_cdev_config_port_vf into 2 functions with locking added (#2). - improve description in sysfs doc to avoid misunderstanding (#3). - switch to boolean in sysfs entry store function (#3). - remove dev_dbg in init/uinit callback function (#7, #9, #11). - remove uinit callback which does does nothing (#8, #9) Main changes from v2: - update kernel version/date in sysfs doc (patch #4, #5, #8, #10, #11). - add back Documentation patch (patch #12). Main changes from v1: - remove DRV/MODULE_VERSION modifications. (patch #1, #3, #4, #6) - remove argsz from new ioctls. (patch #2) - replace sysfs_create/remove_* with device_add/remove_* for sysfs entries.
