This suspend patch is only support cut off the power of cpu and some external devices, since we still lack power_domain driver, so the other power rail of rk3288 need keep power on. I have tested it on rk3288-evb board, atop next-20141112. goto suspend by type "echo mem > /sys/power/state", vdd_cpu is about 0mv by measuring, so it can be determined in sleep mode, then press power button to wakeup it.
