Re: [PATCH 03/19] ab3550: mfd_cell is now implicitly available todrivers

[Mattias Wallin]

Hi Andres,
Thanks for your input on ab3550. You are absolutely right the platform 
data is not used in mainline right now. However we have a few ab3550 
drivers (regulator, gpadc..) that uses the platform data. They have been 
lying on the shelf for a while now but I at least plan to mainline them 
at some point.

BR,
