Hi Wei
one can look at RTC wake up in unit test and check if these codes are used in
custom software
rtcwakeup.c\mxc_rtc\test - imx-test - i.MX Driver Test Application Software
idle mode usage is described in sect.2.5 Power Management i.MX Linux Reference Manual
"IDLE Mode: This mode is defined as a mode which CPU can automatically enter
when there is no thread running and all high-speed devices are not active."
