Subject: [PATCH v9 0/6] add DFL bus support to MODULE_DEVICE_TABLE()

Patch #1 is a fix of the fields in struct dfl_device & dfl_device_id.

Patch #2, 3, 4 add dfl bus support to MODULE_DEVICE_TABLE(), they also
move the necessary definitions in head file to public folders so that
scatter dfl drivers could use them.

Patch #5 is the dfl driver for N3000 Nios private feature, this is the 
first use case of dfl bus.

Patch #6 is the dfl driver for DFL EMIF private feature.


The patchset version number is jumped because I added the Patch #5 in
this patchset, which has a larger version number.


Main changes from v1: 
- A new patch (Patch #3) to fix the description.
- Rename the dfl-bus.h to dfl.h
- Updated the MAINTAINERS under FPGA DFL DRIVERS.
- Improve comments and minor fixes.

Main changes from v2: 
- Change the bus name from "dfl" to "fpga-dfl", also rename related
  variables, functions ... 
- Changes the data type of fpga_dfl_device_id.type from u8 to u16 
- Explicitly defines the values of enum fpga_dfl_id_type
- Delete the comments for the valid bits of type & feature_id
- changes MODALIAS format for fpga dfl devices

Main changes from v3: 
- Change the bus name back to "dfl".
- Add 2 patches (#5, 6) for dfl drivers.
- Delete the retimer FEC mode configuration via module_parameter for 
  Patch #5
- Merge the patch "Make m10_n3000_info static" (https://lore.kernel.org/linux-fpga/52d8411e-13d8-1e91-756d-131802f5f445@huawei.com/T/#t)
  into Patch #5
- Add static prefix for emif attributes macro for Patch #6
