[PATCH v4 0/3] arm64: dts: qcom: eliza-evk: Enable PCIe0 and PCIe1 with M.2 and TC9563 switch

[Krishna Chaitanya Chundru]

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.

This seris Depends-on:

Changes in v4:
- Added new line and used pcie port names as pcieN_portM (Konrad).
- Link to v3: https://patch.msgid.link/20260721-eliza_evk-v3-0-92b10038f13d@oss.qualcomm.com

Changes in v3:
- Clubbed pcie nodes to this series (Bjorn A)
  (https://lore.kernel.org/all/20260708-eliza_dt-v2-1-e6281da26408@oss.qualcomm.com/)
- Added comment for PERST (Mani).
- Extended ranges property for pcie1 (Konrad).
- Link to v2: https://patch.msgid.link/20260708-eliza_evk-v2-0-c599246ceba1@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.
- Link to v1: https://patch.msgid.link/20260703-eliza_evk-v1-0-7624440bd76d@oss.qualcomm.com

[PATCH v4 1/3] arm64: dts: qcom: eliza: Add PCIe PHY and controller nodes

[Krishna Chaitanya Chundru]

Eliza supports two PCIe instances: one 8GT/s x1 (PCIe0) and one 8GT/s x2
(PCIe1). Add PCIe controller and PHY nodes for both instances, and update
the GCC clock references to use the newly added PHY nodes instead of
placeholder zeros.

arm64: dts: qcom: eliza: Add PCIe PHY and controller nodes

This commit introduces PCIe controller and PHY nodes for the Eliza platform.
It also updates the GCC clock references to point to the newly added PHY
nodes instead of placeholder zeros.

[Severity: High]
Is a msi-map property missing from this pcie0 node?

Without the msi-map property, the kernel's PCI OF core cannot establish an
MSI domain for the PCIe bus. Will this cause MSI/MSI-X interrupts to fail
for all connected PCIe endpoints, forcing them to fall back to legacy INTx
interrupts if supported?

[Severity: High]
Is a msi-map property also missing from this pcie1 node?

Similar to pcie0, omitting this property might prevent modern devices like
NVMe drives that exclusively rely on MSIs from functioning correctly on
this controller.

[PATCH v4 2/3] arm64: dts: qcom: eliza-evk: Add PCIe0 with M.2 E key connector

[Krishna Chaitanya Chundru]

The Eliza EVK board features an M.2 E key connector connected to PCIe0.
Enable the PCIe0 root port and its QMP PHY with the necessary RPMH
regulator supplies. The M.2 slot's 3.3V supply rail is GPIO-controlled
via a TCA9538 I/O expander on I2C4.

The M.2 E key slot hosts a WLAN card connected over PCIe and a Bluetooth
device connected over UART. Model the connector using the
pcie-m2-e-connector binding, wiring the PCIe root port and UART5 for
the respective interfaces.

[Severity: High]
Does this GPIO polarity accidentally invert the active-low semantics for the
M.2 Bluetooth RF kill signal?

The M.2 specification defines W_DISABLE2# as an active-low signal. Since
the pwrseq-pcie-m2 driver initializes this GPIO with GPIOD_OUT_HIGH (logical 1)
and enables the Bluetooth device by writing a logical 0, configuring it as
GPIO_ACTIVE_HIGH means a logical 0 translates to a physical LOW signal.

This physical LOW would then disable the radio in hardware right when the
driver intends to enable it. Should this be GPIO_ACTIVE_LOW to match the
w-disable1-gpios polarity and the specification?

[PATCH v4 3/3] arm64: dts: qcom: eliza-evk: Add PCIe1 with TC9563 PCIe switch

[Krishna Chaitanya Chundru]

The Eliza EVK board connects PCIe1 (8GT/s x2) to a Toshiba TC9563
PCIe switch. Enable PCIe1 and its QMP PHY nodes.

TC9563 uses I2C (at address 0x77 on I2C4) for its management interface.

Override the base iommu-map with the expanded set covering all the
switch's downstream ports (0x1400-0x1408 SID range).

The TC9563 RESX# and PERST# are OR-ed internally to assert reset on the
switch. Use TC9563 RESX# pin via a TLMM GPIO and skip wiring PERST#
from the PCIe controller.

[Severity: Low]
Are these leaf PCI endpoints supposed to have PCI-to-PCI bridge properties?

The devicetree parser and schema validation tools might incorrectly interpret
these leaf PCI endpoints as PCI-to-PCI bridges due to the presence of
device_type = "pci", #address-cells, #size-cells, and ranges properties on
nodes that represent endpoint functions rather than buses.

>   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.

>   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).
