Hi Mark

Sorry for the belated update.
As you said, constantly checking dvsok pin and waiting it to active is
not a good idea, so I remove the dvsok pin in latest patch.
This patchset have been tested on ChromeBook, the overshoot has
disappeared on the boards with dvs pin. And for the other boards without
dvs pin, the overshoot alse significantly reduced to a negligible level.

Changes in v4:
- Remove the description about dvs-ok
- remove dvsok pin
- add support gradual adjustment

Changes in v3:
- Modify the syntax error

Changes in v2:
- increase description about dvs pins
- modify the multiline commenting

  regulator: rk808: fixed the overshoot when adjust voltage
