Hi David,

in addition to Wolfgang's comments:

Structure is not used, and probably does not match your board. You
should drop it.

Consider to put these defines in include/asm/arch-mx51/iomux.h. They
could be usefult for other boards, too.

Comment is misleading. Remove what is not needed.

Add spaces when needed.

Probably it is better (and in mx51evk, too) to remove the #ifdef,
because we need to initialize the pmic, else some functionalities cannot
work. It is mandatory that power_init is called.

Is this structure really used ? I have not seen in code. Or does it come
only from mx51evk ? You can remove the whole file, if it is not needed.
