Hello,

This series adds the device-tree support for enabling PCIe and USB
functionality on J722S-EVM.

Since AM62P and J722S SoCs share most of the peripherals, the files have
been renamed to indicate the same. The main domain peripherals on both
SoCs that aren't shared are present in the "soc-main.dtsi" files.
This change has been made based on Roger's feedback at:
https://lore.kernel.org/r/f52d9569-a399-422f-9cf0-b0bf69b64d18@kernel.org/

This series has been tested on J722S-EVM for PCIe and USB functionality:

v5:
https://lore.kernel.org/r/20240604085252.3686037-1-s-vadapalli@ti.com/
Changes since v5:
- Rebased series on linux-next tagged next-20240612.
- Collected Acked-by/Reviewed-by tags from v4 series.
- k3-am62p.dtsi is left as-is, instead of changing it to
  k3-am62p-j722s-common.dtsi.
- Renamed k3-am62p-thermal.dtsi to k3-am62p-j722s-common-thermal.dtsi.
- Based on Vignesh's suggestion at:
  https://lore.kernel.org/r/9e7d3f9b-c762-40cd-9d0d-2f071aa3c371@ti.com/
  and at:
  https://lore.kernel.org/r/79eedaea-bf4f-4a20-8a52-751ce7187523@ti.com/
  the following is the file hierarchy in the current series:
  k3-am62p.dtsi = k3-am62p-j722s-common-{main,mcu,wakeup}.dtsi +
  		  k3-am62p-main.dtsi
  k3-am62p5.dtsi = CPUs + k3-am62p.dtsi
  k3-j722s.dtsi = CPUs + CBASS-Ranges +
  		  k3-am62p-j722s-common-{main,mcu,wakeup}.dtsi +
		  k3-j722s-main.dtsi

Regards,
Siddharth.
