That does not match the protocol definition: these modes issue the opcode on a single line in single data rate (S), and only the address, dummy and data phases use DTR (D). The "1D" prefix is therefore wrong. Rename them to "1S-xD-xD" so the names reflect that the first phase is single-data-rate on one line, consistent with the "8D-8D-8D" naming for SNOR_PROTO_8_8_8_DTR. This only changes the strings printed by debugfs; no functional behavior is affected.
