Sounds like an implementation detail of the OS. Doesn't belong in DT.

Add "fpga-config-from-dmabuf" property to allow the bitstream configuration from pre-allocated dma-buffer. Signed-off-by: Nava kishore Manne <nava.manne@xilinx.com> --- Documentation/devicetree/bindings/fpga/fpga-region.txt | 2 ++ 1 file changed, 2 insertions(+)
