There's a SPI chip named "N25Q064" with 1.8V and 3V variants N25Q064A11 and N25Q064A13, respectively. The 1.8V has A11 suffixed, and the 3V version has A13 suffixed. The 'A' indicates the process technology which is likely to change without a change of device ID, so it's likely that we'll see something like N25Q064B11 or N25Q064B13 in the future.

Fortunately, the two variants have different JEDEC IDs (0xBA17 and 0xBB17). So at least we can tell them apart via probing.

stefanct and I were discussing how to name this chip couldn't really come up with a good solution. I am thinking that "N25Q064" is sufficient and that we should just re-use the same .name for two chip entries with different .voltage parameters.

Thoughts?
