Add the compatible "intel,socfpga-stratix10-hsotg" to the DWC2
implementation, because the Stratix DWC2 implementation does
not support clock gating. This compatible is used with generic
snps,dwc2.

Missing changelog, missing versioning. This is v3 or v4.

So you just sent the same patch as before. I pointed you to the proper
solution with compatibility.



Best regards,

No. not the same.
I don't understand why SoC specific compatible "intel,socfpga-agilex-hsotg" is able to be added, but the SoC specific compatible "intel,socfpga-stratix10-hsotg" is not allowed.

You said "Where is SoC specific compatible?"
Now, I add the SoC specific compatible "intel,socfpga-stratix10-hsotg", but why it is still not reasonable.

Thanks,
Limeng

I had a look the doc ,and refer to rk3128.dtsi and commit 5032b269203287c17064d33c72be1ebf30c04a95.
So I think it needs to add " intel,socfpga-stratix10-hsotg" Documentation/devicetree/bindings/usb/dwc2.yaml.
But if you think it is not reasonable, could you please show what is your modification for the dwc2.yaml.

Thanks,
Limeng
