[SRU][J:linux-xilinx-zynqmp][PATCH 0/1] [KD240] Fix kernel error found `zynqmp-display fd4a0000.display: no PHY found`

[Wei-Lin Chang]

BugLink: https://bugs.launchpad.net/bugs/2121647

SRU Justification

[Impact]

Kernel error `zynqmp-display fd4a0000.display: no PHY found` is found after booting into system.

ubuntu at kria:~$ sudo dmesg --level err
...
[ 6.416868] zynqmp-display fd4a0000.display: no PHY found <--------------This line
...

[Fix]

* Backport 7cb2235eaf5a1b22 from git at github.com:Xilinx/linux-xlnx.git.
When SOM dt is combined with kd240 overlay DPSUB is enabled but kd240 has
no DP wired that's why change disable it via status property.

[Test Plan]

* Checked error message is gone after applying the patch.

[Where problems could occur]

* Turning off nonexistent hardware in DT, low potential for regression.
