    ENGR00241003-1 mx6: need to add delay in LDO voltage setting · c03a6de3
    Anson Huang authored
    1.LDO ramp up time may be modified by ROM code
    according to fuse setting, cpu freq driver use
    fixed delay time which assume the LDO ramp up time
    is the reset value of ANATOP register, need to set
    it to reset value in regulator init.
    
    2.The regulator set voltage should take care of
    the ramp up time, calculate the ramp up time based
    of register setting and to the delay, make sure that
    when the set voltage function return, the voltage is
    stable enough.
    
    3.CPUFreq no need to use delay, it is already taken
    care by regulator voltage setting.
