Subject: [PATCH v7 0/2] Lattice sysCONFIG SPI FPGA manager

Add support to the FPGA manager for programming Lattice FPGAs over slave
SPI sysCONFIG interface. ECP5 and MachXO2 are supported.

WARNING: I only have HW with ECP5, so can't vouch for the MachXO2.
	 MachXO2's support is based on existing machxo2-spi.c and
	 publicly available documentation, it's not tested on real
	 hardware.

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
  v6 -> v7:
    * ecp5-spi.c -> lattice-sysconfig-spi.c. Reworked to represent
      generalized sysCONFIG port with implementations for ECP5 and
      MachXO2
    * lattice,ecp5-fpga-mgr.yaml -> lattice,sysconfig.yaml. Reworked to
      document both ECP5 and MachXO2 sysCONFIG.
    * dt-bindings: remove "Reviewed-by: Krzysztof Kozlowski" tag as doc
      was rewritten by a considerable amount.
