Add documentation to describe Xilinx ZynqMP fpga driver bindings. Signed-off-by: Nava kishore Manne <redacted> --- Changes for v5: -Moved pcap node as a child to firwmare node as suggested by Rob. Changes for v4: -Modified binding description as suggested by Moritz Fischer. Changes for v3: -Removed PCAP as a child node to the FW and Created an independent node since PCAP driver is a consumer not a provider. .../bindings/fpga/xlnx,zynqmp-pcap-fpga.txt | 25 +++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 Documentation/devicetree/bindings/fpga/xlnx,zynqmp-pcap-fpga.txt
