[v2] Add support for Agilex3 SoCFPGA board

[PATCH v2 1/2] dt-bindings: intel: Add Agilex3 SoCFPGA board

Posted by niravkumarlaxmidas.rabara@altera.com 2 months, 4 weeks ago

From: Niravkumar L Rabara <niravkumarlaxmidas.rabara@altera.com>

Add compatible string for Agilex3 SoCFPGA board, which shares the same
architecture as Agilex5 but with two fewer CPU cores.

Signed-off-by: Niravkumar L Rabara <niravkumarlaxmidas.rabara@altera.com>
---

v2 changes:
 - Add separate agilex3 compatible instead of using agilex5 context.

This is confusing, where is the fallback? You said this is fully
compatible with Agilex5, no?

Best regards,
Krzysztof

Yes, I should have "const: intel,socfpga-agilex5" as well for the fallback.

+      - description: Agilex3 boards
+        items:
+          - enum:
+              - intel,socfpga-agilex3-socdk
+          - const: intel,socfpga-agilex3
+          - const: intel,socfpga-agilex5

I will add this in v3.

Thanks,
Nirav
