I'd like to first have a confirmation from :
- Mark (Brown)
- and Lee (Jones)
The confirmation I'm looking for states that :
- the wm9713 should have a part in the mfd tree
- the gpio part should be in drivers/gpio
- the sound soc codecs will remain as is
- if the future driver/mfd/wm9713.c is technically sound, it will be accepted
I remember at least one example where the MFD approach was rejected from mfd
tree for pxa gpios, so I won't work unless I have a confirmation from both
maintainers.
Thanks.
