I think leaving it as DAPM_INPUT will do. Also, if you use DAPM_MIC or any other widget type that takes a callback, the callback can be NULL. I took a quick look at other drivers. The codecs only use non-endpoint types, like INPUT/OUTPUT. It's up to the card to provide endpoints (HP/SPEAKER/LINE/MIC) and route them to the codec INPUT/OUTPUTs.
