Hi all, this series adds support for the Lattice MachXO2 FPGA chip, programmed over Slave SPI.
Tested on my raspberry pi3 + bugblat's pif2 fpga hat. Changes from v1: * fixed all the warnings pointed out by 'checkpatch --strict' and Alan Tull Changes from v2: * convert to BIT() macro and spi_message_init() / trans.delay_usecs 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 | 277 +++++++++++++++++++++ 4 files changed, 314 insertions(+) create mode 100644 Documentation/devicetree/bindings/fpga/lattice-machxo2-spi.txt create mode 100644 drivers/fpga/machxo2-spi.c -- 2.7.4
