Yet again no binding documentation....

Why are we doing this? The MFD cells are a totally Linux specific thing, there's no reason to represent them in the device tree unless they're in some way reusable and the "ab8500-codec" name suggests that's unlikely. Just put the properties on the parent node and instantiate the MFD cell as normal.

Coding style.
- if (!of_property_read_u32(np, "stericsson,earpeice-cmv", &value)) {
switch (value) {
case 950 :
codec->ear_cmv = EAR_CMV_0_95V;
break;

codec->ear_cmv = EAR_CMV_1_10V;

dev_err(dev, "Unsuitable earpiece voltage found in DT\n");
The platform data code picks a default, can't the DT code do the same?
