* regulator: pass additional of_node to regulator_register()Rajendra Nayak2011-11-231-1/+1
| | | | | | | | | | | With device tree support for regulators, its needed that the regulator_dev->dev device has the right of_node attached. To be able to do this add an additional parameter to the regulator_register() api, wherein the dt-adapted driver can then pass this additional info onto the regulator core.

* regulator: Report actual configured voltage to set_voltage()Mark Brown2011-01-121-1/+2
| | | | | | | | | | | 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_voltageAxel Lin2010-10-281-1/+1
| | | | | | | | | | | 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.

* MAX8952 PMIC Driver Initial ReleaseMyungJoo Ham2010-10-281-0/+360
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.
