     On MX6DL, how to verify if kernel has entered into sleep mode? and another question,I have set VSTBY bit on u-boot,but when system is powered up, why PMIC_STBY_REQ is low? and when I press the pwr key, log is as blow:

request_suspend_state: wakeup (3->0) at 3969200866476 (1970-01-19 21:52:43.407821141 UTC)

request_suspend_state: sleep (0->3) at 3979655170811 (1970-01-19 21:52:53.862126475 UTC)

Whatever the transition from wakeup to sleep or from sleep to wakeup, the PMIC_STBY_REQ is low,why ?
