David can advise on the i2c-qup driver support from Qualcomm.
But when that does happen it will use the pinctrl framework to manage
the i2c bus lines.

I will try to push through the pinctrl patch as quickly as possible.
Right now as Linus mentioned, its waiting for his review.

For your vibrator module, do you only rely on the i2c bus lines or
do you also need some pins as reset or interrupt line?

Thanks
