[PATCH v2 0/4] arm64: dts: monaco-arduino-monza: Add support for LGA WiFi/BT module

[Loic Poulain <loic.poulain@oss.qualcomm.com>]

This series describes support for the onboard WiFi/Bluetooth module
present on the Arduino VENTUNO Q (monaco) platform.

The board provides LGA pads for a wireless module. On the VENTUNO Q
these pads are populated with an NFA725B module featuring the
QCA2066 WiFi/BT combo chip. While implemented as an LGA footprint,
the design is functionally compatible with the M.2 Key E.

The NFA725B exposes WiFi over PCIe and Bluetooth over a UART.
Both interfaces are gated through the W_DISABLE1# and W_DISABLE2#
signals, as defined by the M.2 specification and handled here via
the pcie-m2 power sequencer.

This series models the hardware using the existing pwrseq framework
and connector bindings, allowing coordinated PCIe and UART bring-up.

This series depends on:

Changes in v2:
- hci_qca: extract M.2 pwrseq into qca_serdev_get_m2_pwrseq() helper, called
  outside the SoC switch; drop duplicated of_graph logic and redundant
  bt_power NULL checks (Dmitry/Mani)
- dts/bindings: use qcom,pcie-m2-1418-lga-connector (fallback
  pcie-m2-e-connector) instead of the generic M.2 E-key compatible (Mani)
- Link to v1: https://lore.kernel.org/r/20260520-monza-wireless-v1-0-9f6942310653@oss.qualcomm.com
