Missing "qcom,sm8450-dp". As I wrote in the comment to patch 1, I'd suggest having just a single entry here rather than keeping both 8350 and 8450 entries.

While this sounds correct, usually we used the even size here (0x200, 0x400, etc.). Can we please switch to it (especially since sm8350-dp uses even sizes).
