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@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 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 .../ABI/testing/sysfs-bus-dfl-devices-emif | 25 + .../ABI/testing/sysfs-bus-dfl-devices-n3000-nios | 47 ++ MAINTAINERS | 3 +- drivers/fpga/Kconfig | 11 + drivers/fpga/Makefile | 2 + drivers/fpga/dfl-n3000-nios.c | 588 +++++++++++++++++++++ drivers/fpga/dfl.c | 4 +- drivers/fpga/dfl.h | 85 +-- drivers/memory/Kconfig | 9 + drivers/memory/Makefile | 2 + drivers/memory/dfl-emif.c | 207 ++++++++ include/linux/dfl.h | 86 +++ include/linux/mod_devicetable.h | 24 + scripts/mod/devicetable-offsets.c | 4 + scripts/mod/file2alias.c | 13 + 15 files changed, 1023 insertions(+), 87 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-dfl-devices-emif create mode 100644 Documentation/ABI/testing/sysfs-bus-dfl-devices-n3000-nios create mode 100644 drivers/fpga/dfl-n3000-nios.c create mode 100644 drivers/memory/dfl-emif.c create mode 100644 include/linux/dfl.h
