[PATCH v2 0/2] arm64: dts: qcom: eliza-evk: Enable PCIe0 and PCIe1 with M.2 and TC9563 switch

[Krishna Chaitanya Chundru <krishna.chundru@oss.qualcomm.com>]

This series enables PCIe for the Eliza EVK board (CQS SoM on EVK carrier).

The Eliza EVK exposes two PCIe ports:

- PCIe0 drives an M.2 E key connector. The 3.3V supply is GPIO-controlled
  via a TCA9538 I/O expander on I2C4. The slot hosts a WLAN module
  (connected over PCIe) and a Bluetooth device (connected over UART5),
  modelled with the pcie-m2-e-connector binding.

- PCIe1 (8GT/s x2) connects to a Toshiba TC9563 PCIe switch, whose
  management interface sits on I2C4 (address 0x77). The TC9563 RESX# and
  PERST# lines are OR-ed internally; reset is driven via a TLMM GPIO on
  the RESX# pin. The iommu-map covers all downstream switch ports
  (SID range 0x1400-0x1408).

The M.2 WLAN module carries a Qualcomm QCC2072 Bluetooth chip. A device-ID
entry is added to the M.2 power sequencer so the serdev node for the BT
UART interface is created on PCI enumeration.

Bluetooth is enabled with this patch https://lore.kernel.org/all/20260529175822.3366535-1-yepuri.siddu@oss.qualcomm.com/

Changes in v2:
- Drop patch 3, as this is already applied
- Rebase on top of https://lore.kernel.org/all/20260708055017.A90C91F000E9@smtp.kernel.org/
  and remove pincntrl as pincntrl is added in the eliza.dtsi patch and also remove
  pinctrl for resx as this is covered in pcie1_default_state as perst gpio.
