[PATCH v2 0/3] arm64: dts: qcom: Describe the PCIe M.2 Key E connector for Monaco EVK

[Wei Deng]

Add DT support for the PCIe M.2 Mechanical Key E connector on the
Monaco EVK, following the same pattern as the lemans-evk series
(already in linux-next, commits 67f06acf/a6d4bb0a).

Patch 1/3 adds 'compatible = "pciclass,0604"' to the pcieport0 node in
monaco.dtsi, required for downstream DT nodes to be matched to PCI
devices.

Patch 2/3 adds empty labeled endpoints (pcieport0_ep, uart2_ep) to
pcieport0 and uart2 in monaco.dtsi as graph anchors.

Patch 3/3 describes the connector-3 node in monaco-evk.dts, wires the
endpoints via remote-endpoint overrides, adds the vreg_wcn_3p3/
vreg_dcin_12v regulators, and adds the serial1 = &uart2 alias for BT
serdev enumeration.

This series is based on next-20260726.

Changes in v2:
- Move PCIe Root Port and UART2 graph port/endpoint declarations from
  monaco-evk.dts into monaco.dtsi, per Konrad's suggestion. The SoC
  DTSI now defines empty labeled endpoints (pcieport0_ep, uart2_ep) as
  graph anchors, and monaco-evk.dts wires them via remote-endpoint
  overrides. Splits the old patch 2/2 into two patches (new patch 2/3
  for the anchors, patch 3/3 for the EVK board wiring).
- Patch 1/3 unchanged, carries Konrad's Reviewed-by from v1.
- Dropped Dmitry's Reviewed-by on the EVK patch since the port/endpoint
  structure changed; open to re-review.
- Link to v1: https://lore.kernel.org/all/20260727-b4-monaco-evk-m2-v1-v1-0-5429cce68599@xxxxxxxxxxxxxxxx/
