The Radxa Dragon Q6A can boot in EL2, allowing the kernel to access the

You are not adding compatible for LPASS, but for the sound card. And
since you mentioned it, what happens when you boot in EL1?

You need to post bindings for both cases.

Hi Krzysztof,

Thank you for the review. You are right that this patch adds a board-specific compatible for the sound card, not for the LPASS block itself.

For EL1, the default Dragon Q6A DTS already uses the generic
"qcom,qcs6490-rb3gen2-sndcard" compatible, and for the EL2 LPASS-CPU
variant I can also just keep using the generic
"google,sc7280-herobrine" compatible.

Would it be better if I simply drop this binding patch and keep both
cases on their existing generic compatibles instead of introducing
"radxa,dragon-q6a-sndcard"?
