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. >> >> Interesting. Could you please trace, what exactly makes it fail, since specifying bigger region size should not cause such issues. > > Yep I'll trace what's happening. OK weird, I tried with the same sizes as sm8350, and it works fine. Will resend with this fixed. Neil > > Neil > >> >
