[PATCH 1/2] dt-bindings: socfpga: Add the Agilex7 series SoC's

[Dinh Nguyen]

The Agilex7 is a series of devices from Altera that are derived from
the Agilex family.

The Agilex7F device supports PCIE 4.0 and DDR4. The Agilex7I device supports
PCIE 5.0 and DDR4, while the Agilex7M device supports DDR4, DDR5, LPDDR5
and PCIE 5.0.

All other peripherals from these devices are the same as the Agilex
device.

[PATCH 2/2] arm64: dts: Add SoCFPGA Agilex7M devkit

[Dinh Nguyen]

The Agilex7-M SoCDK is largely compatible with the Agilex SoCDK.
Reuse the existing Agilex device tree while disabling the QSPI
controller, which is not present on Agilex7-M.

SoCs?

Please run scripts/checkpatch.pl on the patches and fix reported
warnings. After that, run also 'scripts/checkpatch.pl --strict' on the
patches and (probably) fix more warnings. Some warnings can be ignored,
especially from --strict run, but the code here looks like it needs a
fix. Feel free to get in touch if the warning is not clear.

Why does "7m-socdk" go with "7i" and "7m"? If these are SoCs, then board
using soc 7m cannot use 7i or 7f fallback.

Or board is not using 7m SoC, but then the name is misleading.

And separate question - why previous soc "agilex" is used as fallback?
Even more confusing.

You're right. Sorry for the confusion. The Agilex7M, I, F devices are 
basically "agilex" devices with some few additions (PCIE, DDR5). Maybe I 
should place the Agilex7M/I/F devices into the "agilex" boards area?

Compatibles should be specific and not based on families, thus what is
"intel,socfpga-agilex"? SoC, right?

Then "intel,socfpga-agilex7f" is a new SoC, no?

The Agilex7 is re-branded name for the original Agilex soc,
"intel, socfga-agilex". From a software perspective, they are the same 
device. I looked over the commits to see how I could handle a 
rebranding, but couldn't come up with a conclusion.

I could create a new SoC like you've suggested:

+      - description: Agilex7m boards
+        items:
+          - enum:
+              - altr,socfpga-agilex7m-socdk
+          - const: altr,socfpga-agilex7m
+          - const: altr,socfpga-agilex7

Or I can use the original "intel,socfpga-agilex"?

+      - description: Agilex7m boards
+        items:
+          - enum:
+              - altr,socfpga-agilex7m-socdk
+          - const: altr,socfpga-agilex7m
+          - const: altr,socfpga-agilex

If I create a new "altr,socfpga-agilex7" binding, then I would have to 
add the new binding to a few drivers. But if I use the original
"intel,socfpga-agilex", then no drivers will need to be updated.


Thanks,
Dinh

The family does not matter. What is "socfga-agilex"? One given soc. Not
a family.

So what is "altr,socfpga-agilex7"? Why SoC has two compatibles?

But why? Why are you using one SoC compatible in other context? It's
really no different than all other SoCs.

You anyway MUST have new binding for each device. Please carefully
follow writing bindings and DTS 101.
