From: Alan Tull <atull@xxxxxxxxxxxxxxxxxxxxx> This patch set adds two chunks plus documentation: * FPGA manager core: exports API functions that write an image to a FPGA * DT Overlay support: simple-fpga-bus to handle FPGA from a DT overlay The FPGA manager core is mature enough to be in the regular kernel. simple-fpga-bus is proposed for staging. Changes from v9: * Move FPGA manager core to drivers/fpga * Move simple-fpga-bus to staging/simple-fpga-bus * add TODO * Improvements in fpga_manager_get/put (call module_try_get) * Add flags parameter to .write_complete ops as requested * Documentation improvements * Other minor cleanup More info: The core's API is minimal to start with: only 6 functions. This gives a manufacturer-agnostic interface for programming FPGA's such that higher level interfaces (such as DT Overlays) can be shared. The DT Overlays support exists for the usage where the FPGA will contain some "hardware" that will need drivers. Where that use model is not appealing, the core API can be used to add a different interface. The bindings for the socfpga FPGA manager already are upstreamed as 1b4e119 Alan Tull : doc: add bindings document for altera fpga manager The core FPGA manager support is standalone. The DT Overlays support is dependent on Pantelis's dtc overlay patches from https://github.com/pantoniou/dtc.git and his DT overlays configfs interface patches and fixes from https://github.com/pantoniou/linux-beagle-track-mainline efb0c04 Pantelis Antoniou : gcl: Fix resource linking 85e785e Pantelis Antoniou : ARM: DT: Enable symbols when CONFIG_OF_OVERLAY is used af0321f Pantelis Antoniou : OF: DT-Overlay configfs interface (v5) 4c1c675 Pantelis Antoniou : configfs: Implement binary attributes (v4) Alan Tull (8): usage documentation for FPGA manager core fpga manager: add sysfs interface document add fpga manager core fpga manager: add driver for socfpga fpga manager staging: usage documentation for simple fpga bus staging: add bindings document for simple fpga bus staging: simple-fpga-bus: add TODO document staging: add simple-fpga-bus Documentation/ABI/testing/sysfs-class-fpga-manager | 37 ++ Documentation/fpga/fpga-mgr.txt | 171 ++++++ drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/fpga/Kconfig | 24 + drivers/fpga/Makefile | 9 + drivers/fpga/fpga-mgr.c | 381 ++++++++++++ drivers/fpga/socfpga.c | 616 ++++++++++++++++++++ drivers/staging/Kconfig | 2 + drivers/staging/Makefile | 1 + .../Documentation/bindings/simple-fpga-bus.txt | 83 +++ .../Documentation/simple-fpga-bus.txt | 58 ++ drivers/staging/simple-fpga-bus/Kconfig | 14 + drivers/staging/simple-fpga-bus/Makefile | 5 + drivers/staging/simple-fpga-bus/TODO | 13 + drivers/staging/simple-fpga-bus/simple-fpga-bus.c | 330 +++++++++++ include/linux/fpga/fpga-mgr.h | 127 ++++ 17 files changed, 1874 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-class-fpga-manager create mode 100644 Documentation/fpga/fpga-mgr.txt create mode 100644 drivers/fpga/Kconfig create mode 100644 drivers/fpga/Makefile create mode 100644 drivers/fpga/fpga-mgr.c create mode 100644 drivers/fpga/socfpga.c create mode 100644 drivers/staging/simple-fpga-bus/Documentation/bindings/simple-fpga-bus.txt create mode 100644 drivers/staging/simple-fpga-bus/Documentation/simple-fpga-bus.txt create mode 100644 drivers/staging/simple-fpga-bus/Kconfig create mode 100644 drivers/staging/simple-fpga-bus/Makefile create mode 100644 drivers/staging/simple-fpga-bus/TODO create mode 100644 drivers/staging/simple-fpga-bus/simple-fpga-bus.c create mode 100644 include/linux/fpga/fpga-mgr.h -- 1.7.9.5 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
