Signed-off-by: Nava kishore Manne --- 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 diff --git a/Documentation/devicetree/bindings/fpga/xlnx,zynqmp-pcap-fpga.txt b/Documentation/devicetree/bindings/fpga/xlnx,zynqmp-pcap-fpga.txt new file mode 100644 index 000000000000..3052bf619dd5 --- /dev/null +++ b/Documentation/devicetree/bindings/fpga/xlnx,zynqmp-pcap-fpga.txt @@ -0,0 +1,25 @@ +Devicetree bindings for Zynq Ultrascale MPSoC FPGA Manager. +The ZynqMP SoC uses the PCAP (Processor configuration Port) to configure the +Programmable Logic (PL).
