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,
