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 Changes in v3; * loop unroll machxo2_write() and collate writes in a single spi_sync() 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 | 298 +++++++++++++++++++++ 4 files changed, 335 insertions(+) create mode 100644 Documentation/devicetree/bindings/fpga/lattice-machxo2-spi.txt create mode 100644 drivers/fpga/machxo2-spi.c -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
