2012-04-06regulator: Convert rc5t583 to set_voltageAxel Lin1-8/+15
Not every regulator driver should implement set_voltage_sel callback. See commit e8eef82 "regulator: Provide a selector based set_voltage_sel() operation". For rc5t583, the regulator voltage can be mapped onto selector values with a simple calculation, thus implement set_voltage is better than set_voltage_sel.

2012-04-05regulator: Support set_voltage_time_sel for drivers implement set_voltageAxel Lin1-28/+31
In currently implementation of _regulator_do_set_voltage, set_voltage_time_sel will only be called if set_voltage_sel is implemented. set_voltage_time_sel actually only needs get_voltage_sel to get old_selector. This patch makes regulator core support set_voltage_time_sel for drivers implement either set_voltage or set_voltage_sel.
