I am working on iMX28 design for industrial application (no lcd display etc.) We are running linux 3.1.X on this board. I am interested in exploring possibility of putting MX28 into standby/sleep-mode. I am looking at i.MX28 reference manual (#MCIMX28RM, Rev 1, 2010) and I can't seem to find section/register that describes how to activate those modes. Is there other document that describes how to do power management on i.MX28.
Also has anyone done this successfully while running Linux?
