    Subject[PATCH v10 0/3] Microchip Polarfire FPGA manager
    Date
    Add support to the FPGA manager for programming Microchip Polarfire
    FPGAs over slave SPI interface with .dat formatted bitsream image.

    Changelog:
    v1 -> v2: fix printk formating
    v2 -> v3:
    * replace "microsemi" with "microchip"
    * replace prefix "microsemi_fpga_" with "mpf_"
    * more sensible .compatible and .name strings
    * remove unused defines STATUS_SPI_VIOLATION and STATUS_SPI_ERROR
    v3 -> v4: fix unused variable warning
    Put 'mpf_of_ids' definition under conditional compilation, so it
    would not hang unused if CONFIG_OF is not enabled.
    v4 -> v5:
    * prefix defines with MPF_
    * mdelay() -> usleep_range()
    * formatting fixes
    * add DT bindings doc
    * rework fpga_manager_ops.write() to fpga_manager_ops.write_sg()
    We can't parse image header in write_init() because image header
    size is not known beforehand. Thus parsing need to be done in
    fpga_manager_ops.write() callback, but fpga_manager_ops.write()
    also need to be reenterable. On the other hand,
    fpga_manager_ops.write_sg() is called once. Thus, rework usage of
    write() callback to write_sg().
    v5 -> v6: fix patch applying
    I forgot to clean up unrelated local changes which lead to error on
    patch 0001-fpga-microchip-spi-add-Microchip-MPF-FPGA-manager.patch
    applying on vanilla kernel.
    v6 -> v7: fix binding doc to pass dt_binding_check
    v7 -> v8: another fix for dt_binding_check warning
    v8 -> v9:
    * add another patch to support bitstream offset in FPGA image buffer
    * rework fpga_manager_ops.write_sg() back to fpga_manager_ops.write()
    * move image header parsing from write() to write_init()
    v9 -> v10:
    * add parse_header() callback to fpga_manager_ops
    * adjust fpga_mgr_write_init[_buf|_sg]() for parse_header() usage
    * implement parse_header() in microchip-spi driver
