[PATCH v2 0/4] ARM64: dts: intel: agilex5: add nodes and new board

[Steffen Trumtrar]

This series adds the gpio0 and gmac nodes to the socfpga_agilex5.dtsi.

An initial devicetree for a new board (Arrow AXE5-Eagle) is also added.
Currently only QSPI and network are functional as all other hardware
currently lacks mainline support.

Changes in v2:
- fix node names according to dtb_check
- remove gpio 'status = disabled'
- mdio0: remove setting of adi,[rt]x-internal-delay-ps. 2000 is the
  default value
- add Acked-by to dt-binding
- Link to v1: https://lore.kernel.org/r/20241030-v6-12-topic-socfpga-agilex5-v1-0-b2b67780e60e@pengutronix.de

[PATCH v2 2/4] arm64: dts: agilex5: add gmac nodes

[Steffen Trumtrar]

The Agilex5 provides three Synopsys XGMAC ethernet cores, that can be
used to transmit and receive data at 10M/100M/1G/2.5G over ethernet
connections and enables support for Time Sensitive Networking (TSN)
applications.

That's odd compatible, this is not Arria10 SoC, neither Stratix 10.

Yes, it is. The socfpga-dwmac.txt says "Arria10/Agilex/Stratix10 SoCs" should use "altr,socfpga-stmmac-a10-s10".

So, how to proceed? Adding a "altr,socfpga-stmmac-agilex5" to the binding doc and driver?
And converting the txt to yaml, because touched it last?


Best regards,
Steffen

[PATCH v2 4/4] arm64: dts: agilex5: initial support for Arrow AXE5-Eagle

[Steffen Trumtrar]

The Arrow AXE5-Eagle is an Intel Agilex5 SoCFPGA based board with:

   - 1x PCIe Gen4.0 edge connector
   - 4-port USB HUB
   - 2x 1Gb Ethernet
   - microSD
   - HDMI output
   - 2x 10Gb SFP+ cages

As most devices aren't supported mainline yet, this is only the initial
support for the board.
