I am able to wakeup using gpio-key on my mx51-babbage system if I comment out the most of the drivers except for the gpio-keys driver. Yes, there are additional cpufreq and code that needs to get run in IRAM for mx51, which I will add on to this patch. This is just the initial patch to put the SoC in to suspend and have other developers add to it.
