[PATCH v2 0/4] arm64: qcom: x1e80100-qcp: Add power supply and sideband signals for PCIe RC

[Wenbin Yao]

The first patch enables the PCI Power Control driver to control the power
state of PCI slots. The second patch adds the bus topology of PCIe domain 3
on x1e80100 platform. The third patch adds perst, wake and clkreq sideband
signals, and describe the regulators powering the rails of the PCI slots in
the devicetree for PCIe3 controller and PHY device. The fourth patch adds
qref supply for PCIe PHYs.

The patchset has been modified based on comments and suggestions.

Changes in v2:
- Select PCI_PWRCTL_SLOT by ARCH_QCOM in arch/arm64/Kconfig.platforms in
  Patch 1/4.
- Add an empty line before pcie3port node in Patch 2/4.
- Rename regulator-pcie_12v regulator-pcie_3v3_aux and regulator-pcie_3v3
  in Patch 3/4.
- Add Patch 4/4 to describe qref supply of PCIe PHYs.
- Link to v1: https://lore.kernel.org/all/20250320055502.274849-1-quic_wenbyao@quicinc.com/
