[PATCH v3 0/3] arm64: dts: qcom: eliza-evk: Enable PCIe0 and PCIe1 with M.2 and TC9563 switch
From: Krishna Chaitanya Chundru
Date: Tue Jul 21 2026 - 05:35:32 EST
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@xxxxxxxxxxxxxxxx/

Changes in v3:
- Clubbed pcie nodes to this series (Bjorn A)
(https://lore.kernel.org/all/20260708-eliza_dt-v2-1-e6281da26408@xxxxxxxxxxxxxxxx/)
- Added comment for PERST (Mani).
- Extended ranges property for pcie1 (Konrad).
- Link to v2: https://patch.msgid.link/20260708-eliza_evk-v2-0-c599246ceba1@xxxxxxxxxxxxxxxx
Changes in v2:
- Drop patch 3, as this is already applied
- Rebase on top of https://lore.kernel.org/all/20260708055017.A90C91F000E9@xxxxxxxxxxxxxxx/
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.
- Link to v1: https://patch.msgid.link/20260703-eliza_evk-v1-0-7624440bd76d@xxxxxxxxxxxxxxxx
