The region 0x85fe0000 + 0x20000 seems to be command db, which should be
described on its own. So please reduce the size to 0x20000.

smem_mem: memory@86000000 ?

Should I update kernel docs as well to say all nodes should
have memory has default name? Just followed what was done in
msm8916 and msm8996.

memory@86200000

+ reg = <0 0x86200000 0 0x2d00000>;
+ no-map;
+ };
+ };

The rest looks good.

Regards,
Bjorn
