| * regulator: s5m8767: Fix to read the first DVS register.Amit Daniel Kachhap2012-12-111-3/+3
| | | | | | | | | | | | | | | | | | This patch modifies the DVS register read function to select correct DVS1 register. This change is required because the GPIO select pin is 000 in unintialized state and hence selects the DVS1 register.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Having a linear_min_sel setting means the first linear_min_sel selectors are invalid. We need to subtract linear_min_sel when use n_voltages to determinate if regulator can change voltage.

Let's support this case in core. This patch adds linear_min_sel in struct regulator_desc, so we can allow specific minimal selector for starting linear mapping. Then extends regulator_[map|list]_voltage_linear() to support this feature. Note that for selectors less than min_linear_index, we need count them to n_voltages so regulator_list_voltage() won't fail while checking the boundary for selector before calling list_voltage callback.

Each phase operates at a 2MHz fixed frequency with a 120 deg shift from the adjacent phase, allowing the use of small magnetic component. Add regulator driver for this device.
