[PATCH v2 0/4] Add Intel Agilex5 SoCDK TSN Config2 board

[muhammad.nazim.amirul.nazle.asmade at altera.com]

From: Nazim Amirul <muhammad.nazim.amirul.nazle.asmade at altera.com>

v2:
 - Replace mac-mode DT property with a board-specific compatible string
   "altr,socfpga-stmmac-agilex5-tsn" to identify gmac1 on the TSN Config2
   board, per Andrew Lunn's feedback.
 - Change phy-mode from "rgmii" to "rgmii-id" on both gmac1 and gmac2,
   since the FPGA GMII-to-RGMII converter provides the TX/RX clock delays
   (acting as MAC-side delays).
 - Add a new patch (3/4) documenting the new MAC compatible string in
   the altr,socfpga-stmmac binding.
 - Fix DTS Makefile indentation (Krzysztof Kozlowski).

This series adds DT binding, device tree, and driver support for the
Intel SoCFPGA Agilex5 SoCDK TSN Config2 board.

The board has two Ethernet ports: gmac2 is a standard RGMII port, while
gmac1 is the TSN port. On gmac1, an FPGA GMII-to-RGMII converter sits
between the MAC and the PHY. This converter provides the RGMII TX/RX
clock delays, so phy-mode is set to "rgmii-id". The driver uses the
new "altr,socfpga-stmmac-agilex5-tsn" compatible to detect this setup
and configure the MAC interface selector for GMII while ensuring the
PHY is not asked to add delays a second time.
