suspend-to-ram support for i.MX6Solo running yocto dora 3.10.9 BSP

This is a custom board using a i.MXSolo TO1.1 that used the Sabresd as a reference, I can run:


/ # echo mem > /sys/power/state


To enter the suspend to ram state on the reference board, however trying this on the custom board results in:


/ # echo mem > /sys/power/state

sh: write error: No such device


This worked fine on the custom board running 3.0.35, the kernel seems to be configured correctly to support power management.  Any ideas what I might be missing to enable this?
