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
