Hi Michal, Thanks for trying to fix this.

A device tree doesn't contain pointers, and it doesn't say anything about the size of a pointer on a platform that uses that device tree. phandles are not pointers, they are handles, and they are always 32-bit. So this code is just wrong on 64-bit, you can't safely cast from a 64-bit pointer to a phandle. But I think this warning has actually been fixed differently by commit: 866bfc75f40e ("powerpc: conditionally compile platform-specific serial drivers") If you're still seeing the warning let me know. cheers
