[SRU][J:linux-xilinx-zynqmp][PATCH 0/1] [KR260] Kernel error found 'OF: graph: no port node found in /axi/display at fd4a0000'

[Wei-Lin Chang]

SRU Justification

[Impact]

Found Kernel error 'OF: graph: no port node found in /axi/display at fd4a0000'.

ubuntu at kria:~$ sudo dmesg --level err
...
[ 6.575032] OF: graph: no port node found in /axi/display at fd4a0000 <--------- Here
...

[Fix]

* Backport 1f367ee9554af5d6 from mainline
The DPSUB DT bindings now specify ports to model the connections with
the programmable logic and the DisplayPort output. Add them to the
device tree.

[Test Plan]

* Checked error message is gone after applying the patch.

[Where problems could occur]

* DT update, low potential for regression.
