The Wolfson WM9713 provides 8 GPIOs. If the gpiolib is compiled in the kernel, declare a gpio chip.

You should probably make a seperate driver within GPIO for this and then tie the two together, using an MFD. I appreciate that is more work but it is likely a nicer solution overall.
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.
