Re: [PATCH v2 02/13] da850: pruss platform specific additions.

Hello,

Can we not have the PRU UIO also as a part of the MFD framework.
I know that the UIO is not really a device, but I feel its incorrect to 
register the same device twice.
Instead we can have a single entry as the MFD framework and the UIO, as a 
child device, based upon the MFD driver APIs.

All that we need to do is add an entry into the da8xx_pruss_devices 
structure
and the MFD driver will do the rest to get the UIO probe called.
