Subject: [PATCH v9 0/2] Lattice sysCONFIG SPI FPGA manager
Date: Tue, 30 Aug 2022 12:54:03 +0300 [thread overview]
Message-ID: <20220830095405.31609-1-i.bornyakov@metrotek.ru> (raw)
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.
v7 -> v8:
* dt-bindings: move "program-gpios", "init-gpios" and "done-gpios"
to top-level properties and disallow them for MachXO2 variant.
v8 -> v9:
* dt-bindings: "program-gpios", "init-gpios" and "done-gpios" are
now optional for both ECP5 and MachXO2
* lattice-sysconfig-spi.c -> sysconfig-spi.c + sysconfig.c +
sysconfig.h
** reworked to be one sysCONFIG FPGA Manager rather than two
distinct ECP5 and MachXO2 managers
** splitted to port type agnostic sysconfig.c and SPI-specific
sysconfig-spi.c
** command transfer function moved to callback for ease of
adding another port type, such as I2C
