It's worth noting that this patch is based on board file of Origen in 
Linaro tree

http://git.linaro.org/gitweb?p=landingteams/working/samsung/kernel;a=summary 
branch samsung-linux-3.6-2012.10

and not confirmed with respective board schematics (although verified 
working on an Origen board).

Personally I find these two consumers, which are supposed to provided with 
completely different voltages, connected to a single regulator a bit 
suspicious, so someone who know details of this board should ack or 
correct this patch.

Best regards,
