Exact, must fix.
> > 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. > >> + reg = <0 0xae90000 0 0xfc>, >> + <0 0xae90200 0 0xc0>, >> + <0 0xae90400 0 0x770>, >> + <0 0xae91000 0 0x98>, >> + <0 0xae91400 0 0x98>; > > > 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).
I don't have access to registers layout for HDK8450 but the system freezes when using even sizes, using the exact register size works fine.
