I am running Linux3.10.17 on imx6sl evk. I am trying to put imx6sl evk into a low power mode when the system become idle. when configuring the kernel, I enabled the following PM related options-
I understand that Freescale provides unit tests for PM functions by "echo xxxx > /sys/power/state". But I need something working automatically, which I think "CONFIG_PM_AUTOSLEEP=y" sounds like does, but it seems doing nothing. Do I need extra steps to enable auto-sleep mode on Linux3.10.17?
