These should be using regulator_map_voltage_linear().

This looks like it should be regulator_is_enabled_regmap() and similarly
for the other enable/disable operations.

regulator_get_voltage_sel_regmap()

Should be set_voltage_sel(), really set_voltage_sel_regmap()

regulator_set_voltage_time().

regulator_set_voltage_sel_regmap()

You should register all the regulators unconditionally rather than only
registering the ones in platform data, this allows people to read the
state of the device even if they can't control it.
