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 v7: * misc style fixes, among which: * static const u8 cmd[] * #ifdef DEBUG ... #endif reorder * introduction of get_err_string() * direct returns to reduce line count * indentation 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 | 8 + drivers/fpga/Makefile | 1 + drivers/fpga/machxo2-spi.c | 388 +++++++++++++++++++++ 4 files changed, 426 insertions(+) create mode 100644 Documentation/devicetree/bindings/fpga/lattice-machxo2-spi.txt create mode 100644 drivers/fpga/machxo2-spi.c -- 2.7.4
