2011-05-27regulator: Fix _regulator_get_voltage if get_voltage callback is NULLAxel Lin
In the case of get_voltage callback is NULL, current implementation in _regulator_get_voltage will return -EINVAL. Also returns proper error if ret is negative value.

2011-05-27REGULATOR: TWL6025: add support to twl-regulatorGraeme Gregory
Adding support for the twl6025. Major difference in the twl6025 is the group functionality has been removed from the chip so this affects how regulators are enabled and disabled. The names of the regulators also changed. The DCDCs of the 6025 are software controllable as well. Since V1 Use the features variable passed via platform data instead of calling global function. Change the very switch like if statements to be a more readable switch statement. Since V2 twl6025 doesn't use remap so remove it from the macros. Since V3 enable/disable functions for 4030/6030 were seperated upstream so rebase on top of this. Change DCDC reference to SMPS as this is used in TRM. Change list_voltage slightly to have less code.

2011-05-27regulator: Remove ↵Axel Lin
MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros In current implementation, the original macro implementation assumes the caller pass the parameter starting from 1 (to match the register names in datasheet). Thus we have unneeded plus one then minus one operations when using MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros.

2011-05-27regulator: If we can't configure optimum mode we're always in the best oneMark Brown
If either a regulator driver can't tell us what the optimum mode is (or doesn't have modes in the first place) or the system doesn't allow DRMS changes then it's more helpful for users to just say that we're in the optimal mode, even if it's from a selection of one. Still report errors if the process of picking and setting a mode changes as this may indicate that we're stuck in a low power mode and unable to deliver a higher current that the consumer just asked for.

2011-05-27regulator: Support voltage offsets to compensate for drops in systemMark Brown
Some systems, particularly physically large systems used for early prototyping, may experience substantial voltage drops between the regulator and the consumers as a result of long traces in the system. With these systems voltages may need to be set higher than requested in order to ensure reliable system operation. Allow systems to work around such hardware issues by allowing constraints to supply an offset to be applied to any requested and reported voltages. This is not ideal, especially since the voltage drop may be load dependant, but is sufficient for most affected systems, it is not expected to be used in production hardware. The offset is applied after all constraint processing so constraints should be specified in terms of consumer values not physically configured values.

This actually fixes an off-by-one bug while accessing mc13892_regulators array. For example, In mc13892_regulator_probe, we use MC13892_VCAM as array index of mc13892_regulators array. mc13892_regulators[MC13892_VCAM].desc.ops->set_mode = mc13892_vcam_set_mode; Currently, it access mc13892_regulators[12] ,which is VAUDIO not VCAM.
