Subject: [PATCH v7 0/8] Add PCIe, SERDES and USB DT support for J722S

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:

Sanity testing on AM62P5-SK with this series:

v6:
https://lore.kernel.org/r/20240612132409.2477888-1-s-vadapalli@ti.com/
Changes since v6:
- Rebased series on linux-next tagged next-20240613.
- Collected Acked-by tags from v6 series.
- Based on Roger's suggestion at:
  https://lore.kernel.org/r/d4c33ee4-1e91-40e5-90c8-bd793bcf34ff@kernel.org/
  in order to avoid overriding device-tree node properties, the
  properties that are different across AM62P and J722S have been moved
  from the k3-am62p-j722s-common-main.dtsi file to the respective
  k3-{soc}-main.dtsi files.
  PATCH 5/8 from the v6 series with the subject:
  arm64: dts: ti: k3-j722s: Move MAIN domain overrides to k3-j722s-main.dtsi
  is replaced by PATCH 8/8 of this series corresponding to the suggestion.

Regards,
Siddharth.
