Given this relates to the AVDD voltage feels it is very unlikely to change at runtime. Do we expect it to? Otherwise it might be better added as a DT entry.

Again the polarity of the headphone detect is not going to change at runtime so this should probably be a DT entry.
- SOC_SINGLE("Headphone Switch EN", WM8971_ADCTL2, 6, 1, 0),
I am less clear on whether or not this should be a control or a DT entry, so as long as you are happy this is consistent with the usage.
