[PATCH v13 0/6] simple fpga bus and fpga bridge framework

From: atull
Date: Tue Nov 03 2015 - 12:18:27 EST

From: Alan Tull <atull@xxxxxxxxxxxxxxxxxxxxx>

These patches are too late for this merge window; I'm submitting
them for those who are reviewing, especially the bindings.

Changes since v12:
Change DT property from "init-val" to "bridge-enable"
Use proposed DT common property "firmware-name" instead of "fpga-firmware"
Clean up cruft from simple-fpga-bus DT bindings example
Support Simple FPGA Bus when FPGA Bridges are compiled out.
Cleanup and nits

The Simple FPGA Bus provides a manufacturer-agnostic interface for
reprogramming FPGAs using Device Tree Overlays. It uses the FPGA Bridge
Framework and the upstreamed FPGA Manager Framework. In the case where
FPGA Bridges are not needed, they don't need to be specified in the DT
and can compiled out, if desired.

Alan Tull (6):
fpga: add usage documentation for simple fpga bus
fpga: add bindings document for simple fpga bus
fpga: add simple-fpga-bus
fpga: add fpga bridge framework
ARM: socfpga: add bindings document for fpga bridge drivers
ARM: socfpga: fpga bridge driver support
