Subject: [PATCH v4 1/3] arm64: dts: qcom: Add interconnect nodes for SDX75

Add interconnect nodes to support interconnects on SDX75.
Also parallely add the interconnect property for UART required
so that the bootup to shell does not break with interconnects
in place.

No qup-config?

My brain compiler says this would cause a dt checker warning, at least
on next-20231012.

If I check the tip, then there is only one interconnect entry.
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/soc/qcom/qcom%2Cgeni-se.yaml#L50
For the debug uart, the qup-config is added.
I did check the dtbs_check before sending these patches.
Please let me know if I am missing anything.

Thanks,
Rohit.

Oh, my brain compiler was correct, but for the wrong input data :)

I thought you added this property to the UART itself, not to the QUP
controller. Yes, you're right.
