Yeah, LPDDR5 is a nice argument. Let's go with the array approach (so LPDDR3). Julius, Official deprecation is needed, because the property might be used also in other projects or customers. But this is not a big deal - we will just keep old property for some time. Will you send a patch for it? Best regards, Krzysztof
