Maybe I should modify the sentence as below that makes it clear. "The compatible field should be added in the at24.c for specific chips.".
I quote Andy's words in patch v2: "The current at24 driver has no address width support, thus, reusing same (allocated) IDs (non-DT case) is hard."
This is the reason that I submitted the patch.
Thanks
