Subject: [PATCH v7 0/2] Microchip Polarfire FPGA manager
Date: Tue, 22 Mar 2022 07:32:17 +0300	[thread overview]
Message-ID: <> (raw)

Add support to the FPGA manager for programming Microchip Polarfire
FPGAs over slave SPI interface with .dat formatted bitsream image.

  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
