[PATCH 0/4] arm64: dts: qcom: ipq5018: add Ubiquiti UniFi U6 Enterprise

[Andrei-Alexandru Bleortu]

Add the Ubiquiti UniFi U6 Enterprise, an IPQ5018 access point with two
QCN9074 radios on PCIe (5 GHz and 6 GHz). The first patch documents the
QCN9074's PCI ID in the ath11k PCI binding, so the radios' nodes can
carry the calibration variants their board data is looked up by; the
third labels the PCIe1 root port the way PCIe0's already is.

The Ethernet port (GMAC1 with a QCA8081 PHY) and the IPQ5018's own
2.4 GHz radio are left out until the GMAC and the WCSS remoteproc have
bindings.

The vendor U-Boot only boots Ubiquiti-signed images, so the board was
booted by chainloading from it. Tested on hardware with Linux 7.2 and
the out-of-tree board description these nodes come from: both QCN9074
radios come up with ath11k and their board data selected by these variants,
and the eMMC and the SPI NOR (including U-Boot environment writes) are
in use. The reset button and the accelerometer are described as in the
vendor device tree and were not exercised.

Patch 1 is for the ath11k binding; the rest go through the qcom tree.

The patches were written with an AI coding assistant (Claude Code),
which also drafted the changelogs; the testing above was done on the
device.

[PATCH 1/4] dt-bindings: net: wireless: qcom,ath11k-pci: add QCN9074

[Andrei-Alexandru Bleortu]

QCN9074 is a PCIe 802.11ax radio that boards such as the IPQ5018-based
Ubiquiti UniFi U6 Enterprise solder down, two of them on different
bands. Like the other ath11k PCIe devices, each needs
qcom,calibration-variant to select its board data. Document its PCI ID.

No supplies are added: on these boards the radio's rails are fixed and
not under software control.

[PATCH 3/4] arm64: dts: qcom: ipq5018: label the PCIe1 root port

[Andrei-Alexandru Bleortu]

The root port of pcie0 has a label, the one of pcie1 has none, so a
board cannot attach its PERST# GPIO or a device below it the same way.
Add pcie1_port0.

[PATCH 4/4] arm64: dts: qcom: ipq5018: add Ubiquiti UniFi U6 Enterprise

[Andrei-Alexandru Bleortu]

The Ubiquiti UniFi U6 Enterprise is a ceiling-mount Wi-Fi 6E access point:

- SoC: Qualcomm IPQ5018
- RAM: 1 GiB
- Flash: SPI NOR (boot chain) and eMMC
- 5 GHz: QCN9074 on PCIe0
- 6 GHz: QCN9074 on PCIe1
- Ethernet: one 2.5GbE PoE port, a QCA8081 PHY behind GMAC1
- Accelerometer: ST LIS2DH12
- Button: reset

Describe what mainline supports today. The Ethernet port and the
IPQ5018's own 2.4 GHz radio are left out until the GMAC and the WCSS
remoteproc have bindings; the LED controller and the board MCU on the
I2C bus have none. The QCN9074s carry the calibration variants their
board data is looked up by. The vendor QSEE reserves 4 MiB, twice the
SoC default.

This is pointless commit. The label does not end up in DTB and there is
no user of it.

Drop or squash.
