bae5e9c33f regulator: da903x: Kill da903x_[get|set]_[ldo12|ldo14]_voltage_sel() functions
Now the implementation of da903x_set_voltage_sel, da9030_set_ldo14_voltage_sel,
and da9034_set_ldo12_voltage_sel are exactly the same.

da903x_get_voltage_sel, da9030_get_ldo14_voltage_sel and
da9034_get_ldo12_voltage_sel are exactly the same.

So we can use da903x_[get|set]_voltage_sel and kill other functions.

bca7bbfff3 regulator: core: Allow drivers to set simple linear voltage maps as data
A lot of regulator hardware maps selectors on to voltages with a simple
linear mapping function

    selector = base + (selector * step size)

Provide off the shelf list_voltage() and map_voltage() operations which
use new min_uV and uV_step members in the regulator_desc to implement
this function.

e843fc4616 regulator: core: Allow regulators to provide a voltage to selector mapping
In order to allow more drivers to factor things out into data allow
drivers to provide a mapping function to convert voltages into selectors.
This allows any driver to use set_voltage_sel(). The existing mapping
based on iterating over list_voltage() is provided as an operation which
can be assigned to the new map_voltage() function though for ease of
transition it is treated as the default.

411a2df509 regulator: twl-regulator: make TWL4030_ALLOW_UNSUPPORTED more configurable.
The regulators in the twl4030 can provide some voltage settings
that are not offically supported.
These settings are disabled by default, but can be enabled with
  CONFIG_TWL4030_ALLOW_UNSUPPORTED=y
However
 - that config variable is not mentioned in any Kconfig so cannot
   be used, and
 - a global setting is clumsy - a per regulator setting would be
   better.

So define a new 'feature' flag that a board file can set to enable
these unsupported volatages for boards which need them.

This flag cannot (yet) be set using device-tree.
