rk808 has a dvs function, there are 3 pins for dvs, dvs1 & dvs2 & dvsok.
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.
Changes in v2:
- increase description about dvs pins
- modify the multiline commenting
