Thank you for adding this support. >> >> Is somebody prepping patches to pull in support for i.MX6DQ? > > I can not follow you on this? you mean adding dts files for i.MX6DQ or else? > 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.
