Thank you for adding this support.

Yes, or at least the .dtsi and .h files from arch/arm/boot/dts/.

Your i.MX6UL patch pulled in the files needed for UL, and the same
is needed for i.MX6DQ, i.MX6SX and such.

I have a patch pulling i.MX6DQ files from linux-stable (4.4), but
don't want to jump in the middle if somebody else is doing this.
