The WM8758 chip is almost identical to WM8985 with the difference that it doesn't feature the AUX input. This patch adds the WM8758 support into the WM8985 driver.
The chip selection is done by the I2C name. The SPI probe supports only the WM8985.

They seem to all be used on 8985 as well.
In general I agree with you. But doesn't the order in which snd_soc_add_codec_controls() is called affect the order in which the controls appear in the mixer? I have split the controls in order to preserve the original order of the controls.

All these are set by wm8985_add_widgets() now. Or maybe I didn't quite get what you mean?
Thanks Petr
