Subject: [PATCH v2 0/3] PCIe NTB and USB Overlays for J721E, J742S2 and J784S4

Hello,

This series adds the device-tree overlays for PCIe NTB (Non-Transparent-
Bridge) functionality on J721E, J742S2 and J784S4 SoCs which have
at-least two instances of PCIe that are required for NTB.

The device-tree overlay for switching from Type-C USB interface to Type-A
USB interface on J742S2-EVM and J784S4-EVM is also included in this series.

Series is based on linux-next tagged next-20250226.

v1 of this series is at:
https://patchwork.kernel.org/project/linux-arm-kernel/cover/20250202093636.2699064-1-s-vadapalli@ti.com/
Changes since v1:
- s/epf_bus/epf-bus in the first and second patch of this series since
  node names shouldn't contain underscores.

Regards,
Siddharth.
