Fixed some typos in the i.MX28 PMU code that sets up the VDDD and VDDIO power rails. In addition the VDDD and VDDIO brownout offset values should be divided by a step size before being programmed to the corresponding registers.

Hi Stathis,
your patch looks ok but it is mangled by your e-mailer. See how
patchwork shows your patch at:
http://patchwork.ozlabs.org/patch/173592/
Part of your patch is moved into the comments and some characters are
replaced.
Your patch is surely ok because you use git-format-patch. Can you check
this issue and resend it, possibly using git send-email that avoids
these kind of problems ? Thanks !
Best regards,
Stefano Babic
