Pull regulator updates from Mark Brown:
 "A couple of nice new features this month, the ability to map
  regulators in order to allow voltage control by external coprocessors
  is something people have been asking for for a long time.

   - improved support for switch only "regulators", allowing current
     state to be read from the parent regulator but no setting.

   - support for obtaining the register access method used to set
     voltages, for use in systems which can offload control of this to a
     coprocessor (typically for DVFS).

   - support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments
     TPS65917"

7. Regulator Direct Register Access
===================================
Some kinds of power management hardware or firmware are designed such that
they need to do low-level hardware access to regulators, with no involvement
from the kernel. Examples of such devices are:
- clocksource with a voltage-controlled oscillator and control logic to change
the supply voltage over I2C to achieve a desired output clock rate
- thermal management firmware that can issue an arbitrary I2C transaction to
perform system poweroff during overtemperature conditions
To set up such a device/firmware, various parameters like I2C address of the
regulator, addresses of various regulator registers etc. need to be configured
to it. The regulator framework provides the following helpers for querying
these details.
Bus-specific details, like I2C addresses or transfer rates are handled by the
regmap framework. To get the regulator's regmap (if supported), use :-
struct regmap *regulator_get_regmap(struct regulator *regulator);
To obtain the hardware register offset and bitmask for the regulator's voltage
selector register, use :-
int regulator_get_hardware_vsel_register(struct regulator *regulator,
unsigned *vsel_reg,
unsigned *vsel_mask);
To convert a regulator framework voltage selector code (used by
regulator_list_voltage) to a hardware-specific voltage selector that can be
directly written to the voltage selector register, use :-
int regulator_list_hardware_vsel(struct regulator *regulator,
unsigned selector);
