Normally, the voltage of DCDC1/DCDC2 are controlled by BUCKn_ON_VSEL, when we pull dvs1/dvs2 pin to active, they would be controlled by BUCKn_DVS_VSEL. And the dvsok pin is used to indicate whether regulating has been completed. When dvs1/dvs2 pin change, dvsok would be pull down, and it would be pull up once the regulating is complete.
