I still give my RB for the series. To me the only question is should it be applied to sm8550 or to new SoCs from now on, sa8775p, x1e and derivatives. I take the point on ABI breakage on 8550, so to me it seems fully consistent with Krzysztof's statements on ABI maintenance and indeed the need to expand the features of this driver to do so from the next submission onwards. That can be as simple as schema.yaml if compatible newsoc minItems:1 maxItems:2 8550's ABI is stable and new SoC submissions will support the secure/non-pixel method. --- bod
