Hello,

  from the team:

before PMIC_STBY_REQ assertion, system is ready to enter into DSM mode,

and preparation work have been done (just like stop related clocks, enter DDR

into refresh mode, CPF operation); so,  after PMIC_STBY_REQ assertion, only

need to PMIC power off the related power for chip; and chip will enter into DSM

mode quickly after PMIC_STBY_REQ assertion; 

Regards,

Yuri.
