Subject: [PATCH v4 0/3] Add PCIe3 and PCIe5 support for HAMOA-IOT-EVK board

From: Ziyue Zhang <quic_ziyuzhan@...cinc.com>

This patch series adds support for PCIe3 and PCIe5 on the HAMOA-IOT-EVK
board.

PCIe3 is a Gen4 x8 slot intended for sata controller.
PCIe5 is a Gen3 x2 slot designed for external modem connectivity.

To enable these interfaces, the series introduces the necessary device
tree nodes and associated regulator definitions to ensure proper power
sequencing and functionality.
