[PATCH v10 0/6] add DFL bus support to MODULE_DEVICE_TABLE()

From: Xu Yilun
Date: Thu Oct 15 2020 - 03:21:50 EST


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.


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@xxxxxxxxxx/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

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
