Subject: [PATCH v4 0/4] Add PCIe Overlays for J721E, AM68 and AM69

Hello,

This series adds device-tree overlays for enabling Endpoint mode of
operation of the PCIe Controllers on TI's J721E, AM68 and AM69 SoCs.

Only the second patch of this series has a v3 while the rest of the
patches have been newly introduced in this series. The reason for
grouping patches is the dependency on the Makefile w.r.t. the changes
made in the patches when enabling overlays.

v3:
https://lore.kernel.org/r/20241010100933.2492806-1-s-vadapalli@ti.com/
Changes since v3:
- Rebased on next-20241204.

v2:
https://lore.kernel.org/r/20240222065733.1213434-1-s-vadapalli@ti.com/
Changes since v2:
- Rebased patch on next-20241010.
- Moved vendor specific property "ti,syscon-pcie-ctrl" to the end of the
  node.

v1:
https://lore.kernel.org/r/20240220105006.1056824-1-s-vadapalli@ti.com/
Changes since v1:
- Created a new overlay for PCIE1 based on Andrew's suggestion at:
  https://lore.kernel.org/r/415ee6d4-fe26-4582-80f3-9b503d308fdf@ti.com/
- Updated Makefile to allow applying overlay on
  "k3-j721e-evm-pcie0-ep.dtb"

Series is based on linux-next tagged next-20241204.
