Subject: [PATCH v5 0/7] 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:

v4:
https://lore.kernel.org/r/20240601121554.2860403-1-s-vadapalli@ti.com/
Changes since v4:
- Rebased series on linux-next tagged next-20240604.
- Based on Andrew's feedback at:
  https://lore.kernel.org/r/086fa11e-10f8-463d-8966-1a33a52a3146@ti.com/
  MCU was retained as-is while main and wakeup were changed to MAIN and
  WAKEUP in the respective shared files. Also, newline was added between
  the file description and the Copyright in all the files.
  Collected Acked-by tag for the 1st patch since these changes have been
  made.
- Based on Andrew's feedback at:
  https://lore.kernel.org/r/147d58a6-0cad-47b6-a069-755f835a77e9@ti.com/
  SERDES1 has also been disabled in k3-j722s-main.dtsi similar to SERDES0.
- Based on Andrew's feedback at:
  https://lore.kernel.org/r/183a9d15-939e-433b-84ba-8a64eb8ef3ec@ti.com/
  the `status = "okay";` line has been moved to the end of the
  `pcie0_rc` node referenced in k3-j722s-evm.dts following the updated
  ordering rules. Also, the SERDES1 node has been enabled in the
  k3-j722s-evm.dts file since it has been disabled in the
  k3-j722s-main.dtsi file.

Regards,
Siddharth.
