Instead of adding deprecated schema just correct the DTSes to use snps. The "synopsys" is not even in vendor prefixes. Best regards, Krzysztof

Yeah, it's not, but the driver and some dts'es use it this way. I am not sure that the solution suggested by you is much better than mine. So let's hear the Rob'es opinion out in this matter. @Rob, what do you think? -Sergey > > Best regards, > Krzysztof

I think we should fix the dts files given there's only 5. Rob

The DWC USB3 driver and some DTS files like Exynos 5250, Keystone k2e, etc expects the DWC USB3 DT node to have the compatible string with the "synopsys" vendor prefix. Let's add the corresponding compatible string to the controller DT schema, but mark it as deprecated seeing the Synopsys, Inc. is presented with just "snps" vendor prefix.
