Hi all, this series adds support for the Lattice MachXO2 FPGA chip, programmed over slave SPI.
Tested on a raspberry pi3, beaglebone black (little endian mode) and imx6 hummingboard (big endian mode) + bugblat's pif2 fpga hat (machxo2 7000HC) or tinyfpga A1/A2 (machxo2 256HC / 1200HC), in SPI slave mode with varying bus speed. Changes since v9: * implemented machxo2_spi_state() Paolo Pisati (2): dt: bindings: fpga: add lattice machxo2 slave spi binding description fpga: lattice machxo2: Add Lattice MachXO2 support .../bindings/fpga/lattice-machxo2-spi.txt | 29 ++ drivers/fpga/Kconfig | 7 + drivers/fpga/Makefile | 1 + drivers/fpga/machxo2-spi.c | 413 +++++++++++++++++++++ 4 files changed, 450 insertions(+) create mode 100644 Documentation/devicetree/bindings/fpga/lattice-machxo2-spi.txt create mode 100644 drivers/fpga/machxo2-spi.c -- 2.7.4
