I've now tested this on a client's board which uses the pcm030 with a custom base board (based on the development board) which uses the same codec. It works there. I don't have a discrete touchscreen to wire up to the PCM-973 though. g. -- There is a header on the phytec PCM-973 base board (X20) that brings out aux1, aux2, aux3, aux4 (wiper) ADCs from the wm9712. The ADCs use chip registers the same way the touchscreen does. There is even support for doing this through the wm97xx-core driver (wm97xx_read_aux_adc). If you wanted to test it out I would put a pot or some fixed voltage divider on one of those inputs and give it a try. I don't know what the internal ADC ref is, I think its 1.65V so whatever signal you put in should be less than that.
