[PATCH v6 0/2] Lattice ECP5 FPGA manager

[Ivan Bornyakov]

Add support to the FPGA manager for programming Lattice ECP5 FPGA over
slave SPI interface with .bit formatted uncompressed bitstream image.

ChangeLog:
  v1 -> v2:
    * remove "spi" from compatible string
    * reword description in dt-bindings doc
    * add reference to spi-peripheral-props.yaml in dt-binding doc
    * fix DTS example in dt-bindings doc: 4-spaces indentations, no
      undersores in node names.
  v2 -> v3:
    * fix typo "##size-cells" -> "#size-cells" in dt-bindings example
  v3 -> v4:
    * dt-bindings: reword description
    * dt-bindings: revert props order
  v4 -> v5:
    * dt-bindings: remove trailing dot from title
    * dt-bindings: reword description to avoid driver reference
    * dt-bindings: add "Reviewed-by: Krzysztof Kozlowski" tag
  v5 -> v6:
    * ecp5-spi: lock SPI bus for exclusive usage in
      ecp5_ops_write_init(), release in ecp5_ops_write_complete()
      or on error
