[PATCH v3 0/2] ARM: dts: zynq: Add ALINX AX7Z020B development board

[Pufan Jin <cyan2254650260@gmail.com>]

Add devicetree support for the ALINX AX7Z020B board, built around the
ALINX AC7Z020 system on module with a Zynq-7000 (XC7Z020-2CLG400I) SoC.

Changes in v3:
- Drop the vendor website Link: tags (Krzysztof Kozlowski).
- Drop the empty bootargs property (Krzysztof Kozlowski).
- Rename the USB PHY node from phy0 to phy, as there is only one USB PHY
  on the board (Krzysztof Kozlowski).
- Keep the explicit mdio node under gem0, as requested during the v1
  review and reviewed by Andrew Lunn in v2.  dtc W=1 flags the parent
  node's inherited #address-cells/#size-cells.  DT schema validation
  reports the same Zynq-7000 diagnostics as zynq-zybo-z7.  The MDIO
  layout was also verified on hardware.
- Sort I2C child nodes by address and reorder status/reg properties.
- Add Krzysztof's Acked-by to patch 1.

The "alinx" vendor prefix is already queued in linux-next as commit
1f06cd374a60 ("dt-bindings: vendor-prefixes: Add ALINX vendor prefix"),
so it is not part of this series.

Tested on hardware before the DTS style reordering: SD boot, UART
console, SD card, GbE (900+ Mbps and LED hardware offload), dual CAN,
I2C, QSPI and XADC.
