Subject: [PATCH v12 0/6] add DFL bus support to MODULE_DEVICE_TABLE()

I added back the first 4 patches for DFL driver autoloading cause there are
comments for them and I fixed one place.

Maybe this patchset should be posted together in next pull request, so that
maintainers could see the usecase of include/linux/dfl.h

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

Main changes from v9:
- Add the description for struct dfl_device_id in mod_devicetable.h
- Move the dfl.h from include/linux/fpga to include/linux
- some code refactor and minor fixes for dfl-n3000-nios

Main changes from v10:
- use sysfs_emit instead of sprintf for both patches
- rebase to 5.10-rc1

Main changes from v11:
- Fix the type of driver_data from unsigned long to kernel_ulong_t
- Fixed up header guards to match filename by Moritz
- move the MODULE_DEVICE_TABLE() right after its definition

Xu Yilun (6):
  fpga: dfl: fix the definitions of type & feature_id for dfl devices
  fpga: dfl: move dfl_device_id to mod_devicetable.h
  fpga: dfl: add dfl bus support to MODULE_DEVICE_TABLE()
  fpga: dfl: move dfl bus related APIs to include/linux/dfl.h
  fpga: dfl: add support for N3000 Nios private feature
  memory: dfl-emif: add the DFL EMIF private feature driver
