This series adds an FPGA manager for Altera cyclone FPGAs that can program them using an spi port and a couple of gpios, using Alteras passive serial protocol. Changes from v1: - Changed the name from cyclone-spi-fpga-mgr to cyclone-ps-spi-fpga-mgr This name change was requested by Alan Tull, to be specific about which programming method is being employed on the fpga. - Changed the name of the reset-gpio to config-gpio to closer match the way the pins are described in the Altera manual - Moved MODULE_LICENCE, _AUTHOR, and _DESCRIPTION to the bottom - Added a bitrev8x4() function to the bitrev headers and implemented ARM const, runtime, and ARM specific faster versions (This may end up needing to be a standalone patch) - Moved the bitswapping into cyclonespi_write(), as requested. This falls short of my desired generic lsb first spi support, but is a step in that direction. - Fixed whitespace problems introduced during refactoring - Replaced magic number for initial delay with a descriptive macro - Poll the fpga to see when it is ready rather than a fixed 1 ms sleep Joshua Clayton (5): lib: add bitrev8x4() doc: dt: add cyclone-spi binding document fpga manager: Add cyclone-ps-spi driver for Altera FPGAs ARM: dts: imx6q-evi: support cyclonespi fpga manager: cyclone-ps-spi: make delay variable .../bindings/fpga/cyclone-ps-spi-fpga-mgr.txt | 23 +++ arch/arm/boot/dts/imx6q-evi.dts | 16 ++ arch/arm/include/asm/bitrev.h | 5 + drivers/fpga/Kconfig | 7 + drivers/fpga/Makefile | 1 + drivers/fpga/cyclone-ps-spi.c | 175 +++++++++++++++++++++ include/linux/bitrev.h | 26 +++ 7 files changed, 253 insertions(+) create mode 100644 Documentation/devicetree/bindings/fpga/cyclone-ps-spi-fpga-mgr.txt create mode 100644 drivers/fpga/cyclone-ps-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
