Subject: [PATCH v3 2/3] dt-bindings: fpga: Add bindings for ZynqMP fpga driver

Add documentation to describe Xilinx ZynqMP fpga driver
bindings.

Signed-off-by: Nava kishore Manne <[email protected]>
---
Changes for v3:
-Created patches on top of 5.0-rc5.
No functional changes.
Changes for v2:
-Removed "----" separators.
Changes for v1:
-Created a Seperate(New) DT binding file as
suggested by Rob.

Changes for RFC-V2:
-Moved pcap node as a child to firwmare
node as suggested by Rob.

How about:
Devicetree bindings for Zynq Ultrascale MPSoC FPGA Manager.

ZynqMP or ZynqMp, let's stay consistent here.

How about:
The ZynqMP SoC uses the PCAP (Processor configuration Port) to configure the
Programmable Logic (PL). The configuration uses the firmware interface.

I thought I was told in the review of the firmware binding that is went
away...

There's no DT resources here, so there's no need for this in DT. Just
have the parent (the firmware driver) instantiate the driver.
