Nothing idling for me with your .config.. And it seems slower to boot
compared to omap2plus_defconfig? Maybe because of the extra GPIO
interrupts?

Looks like you have 117 additional entries in .config enabled compared
to omap2plus_defconfig. Maybe go back to omap2plus_defconfig with minimal
changes and verify it idles properly first?

I'm suspecting it's some driver(s) you have enabled causing the
issue.
