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

[Andrei-Alexandru Bleortu <me@andrei-z.com>]

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.
