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
