Waiting period before setting regulator[Reg1_select] =

reg1_V. Power-down uses same timing (Wait time after

turning OFF).

0 : No delay: Wait 0 ms. Then set Reg1 voltage.

1 : Delay: Wait 1 ms (del_time=1: 4 ms). Then set Reg1

voltage.

2 : Delay: Wait 4 ms (del_time=1: 12 ms). Then set Reg1

voltage.

3 : GPIO3 control: Wait 0 ms. Then set Reg1 voltage. Set

gpio_ctrl_xxx=3 (Reg1 controlled by GPIO3)
