2012-11-27regulator: as3711: Fix the logic in as3711_sel_checkAxel Lin
Below equation means the "voltage" is the "smallest" voltage within specific range. ret = DIV_ROUND_UP(min - bottom) / step; voltage = ret * step + bottom; If we do try 1 down when (voltage > max), new voltage is then less than min voltage. Which means the new voltage is not in the requested voltage range. This patch also includes below cleanups: - Use DIV_ROUND_UP - rename variable 'ret' to 'sel' for better readability because as3711_sel_check returns the selector.

2012-11-27regulator: core: Allow specific minimal selector for starting linear mappingAxel Lin
Some drivers (at least 3 drivers) have such variant of linear mapping that the first few selectors are invalid and the reset are linear mapping. 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.

2012-11-21regulator: da9055: Properly handle voltage range that doesn't start with 0 ↵Axel Lin
offset This patch implements map_voltage and list_voltage callbacks to properly handle the case voltage range that doesn't start with 0 offset. Now we adjust the selector in map_voltage() before calling set_voltage_sel(). And return 0 in list_voltage() for invalid selectors. With above change, we can remove da9055_regulator_set_voltage_bits function. One tricky part is that we need adding voffset to n_voltages. Although for the cases "selector < voffset" are invalid, we need add voffset to n_voltage so regulator_list_voltage() won't fail while checking the boundary for selector before calling list_voltage callback.

Moving regulator node parsing to regulator driver in place of parsing it on mfd driver. The motivation for this change are: - MFD core driver should not depends on regulator and able to instantiate device without regulator. - The API for matching regulators are in regulator core and it is good that regulator driver only calls this API. - Regulator specific support should be in regulator driver only to ease any enhancement/modification for regulators. - The regulator driver is now registered as mfd sub device and all regulator registration is done from single probe call.
