[PATCH v2 0/3] arm64: zynqmp: Add support for ALINX EdgeBoard FZ3A

[Pufan Jin]

The ALINX EdgeBoard FZ3A is a single board computer from ALINX based on
the Xilinx Zynq UltraScale+ XCZU3EG SoC.

This series adds the ALINX vendor prefix, documents the board compatible,
and adds a device tree for the board's PS peripherals:

  - UART1 debug console
  - eMMC (HS200) and microSD card
  - GEM3 Ethernet with Micrel KSZ9031 PHY on the MDIO bus
  - I2C0 and I2C1
  - QSPI NOR flash
  - PCIe
  - USB 3.0 host
  - DisplayPort output

The Paddle-Mobile FPGA accelerator is not included. Its PL description
depends on vendor-specific IP and an out-of-tree driver.

Tested on ALINX FZ3A hardware with Linux 7.3.0-rc5: the board boots from
SD card into userspace over the serial console, gem3 negotiates
1000Mbps/Full duplex with phy-mode = "rgmii-id", and the eMMC runs in
HS200 mode.

The base DTB passes CHECK_DTBS=y, and the Xilinx SoC binding passes
dt_binding_check.

Changes since v1:
  - Use the correct vendor prefix 'alinx' instead of 'ebdee', and rename
    the board and DTS file accordingly (Krzysztof Kozlowski)
  - Describe the board as a single board computer with the SoC, DDR4 and
    eMMC on one PCB, not a carrier board with a MYIR SoM (Andrew Lunn)
  - Add the MDIO bus and describe the KSZ9031 PHY with phy-handle
    (Andrew Lunn)
  - Enable eMMC HS200 on sdhci0: drop no-1-8-v, add pinctrl and
    mmc-hs200-1_8v
  - Drop power-source and bias-high-impedance from pinctrl_gem3_default,
    which only produce spurious warnings on the board's pre-2023.1 PM
    firmware
