The driver has a list of devices it is capable of driving. The kernel uses that list to find the right driver. > In the kernels I tried, m25p80 driver is simply not happy with > m25p16 being defined in DT. Please define "not happy". Please show me the kernel log of it being not happy. We need to compare and contrast my kernel log, where it is happy with "st,m25p16" against your kernel log where it is unhappy. Then we might have some clues to understand what is going on.
