This series adds an FPGA manager driver for Xilinx Spartan6 FPGAs that can configure them using an SPI port and two GPIOs. Anatolij Gustschin (2): dt: bindings: fpga: add xilinx slave-serial binding description fpga manager: Add Xilinx slave serial SPI driver Changes in v4: - add Acked-by tags for DT bindings - increase program latency up to 7.5ms for other Xilinx FPGAs - continue to apply CCLK cycles until specified timeout elapses (to cover more possible configuration DONE scenarios) - apply 8 CCLK cycles afer DONE signal - rebased to apply on top of Kconfig/Makefile changes by queued fpga manager patches Changes in v3: - extend example to show the usage in SPI master node, connected to the fpga-region node - use named constant for udelay()/usleep_range() arguments - drop not needed .owner init - correct module licence (GPL v2) - fix build warning with newer gcc (in min() macro) Changes in v2: - corrected gpios properties and node name in example in DT binding document - rebased on v4.10 .../bindings/fpga/xilinx-slave-serial.txt | 44 +++++ drivers/fpga/Kconfig | 7 + drivers/fpga/Makefile | 1 + drivers/fpga/xilinx-spi.c | 198 +++++++++++++++++++++ 4 files changed, 250 insertions(+) create mode 100644 Documentation/devicetree/bindings/fpga/xilinx-slave-serial.txt create mode 100644 drivers/fpga/xilinx-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
