regulator: Report actual configured voltage to set_voltage()

2011-01-12T14:32:59Z

Change the interface used by set_voltage() to report the selected value to the regulator core in terms of a selector used by list_voltage(). This allows the regulator core to know the voltage that was chosen without having to do an explict get_voltage(), which would be much more expensive as it will generally access hardware.

regulator: max8952 - fix max8952_set_voltage

2010-10-28T21:40:32Z

In current implementation, vid is declared as u8, then "vid == -1" is always false, and "vid >= 0" is always true. Thus change it to s8. Signed-off-by: Axel Lin Acked-by: Mark Brown Acked-by: Kyungmin Park Signed-off-by: Liam Girdwood

MAX8952 PMIC Driver Initial Release

2010-10-28T21:40:31Z

MAX8952 PMIC is used to provide voltage output between 770mV - 1400mV with DVS support. In this initial release, users can set voltages for four DVS modes, RAMP delay values, and SYNC frequency. Controlling FPWM/SYNC_MODE/Pull-Down/Ramp Modes and reading CHIP_ID is not supported in this release. If GPIO of EN is not valid in platform data, the driver assumes that it is always-on. If GPIO of VID0 or VID1 is invalid, the driver pulls down VID0 and VID1 to fix DVS mode as 0 and disables DVS support. We assume that V_OUT is capable to provide every voltage from 770mV to 1.40V in 10mV steps although the data sheet has some ambiguity on it.
