No problem.

Are you referring to the following patches?

"dt-bindings: Add GPCv2 power gating driver"
"soc: imx: Add GPCv2 power gating driver"

I've pulled these patches from Shawn's tree to test with, but still
not able to get anything functional. Is there another series I should
be looking at?

Thanks,

Tyler
