Qualcomm Technologies, Inc. PM8008 is an I2C controlled PMIC
containing 7 LDO regulators. Add a PM8008 regulator driver to
support PMIC regulator management via the regulator framework.

Please use a name like spmi_regulator_data :) Or pm8008_regulator_data?
Something that isn't so generic.
Okay.
It seems similar to qcom_spmi-regulator.c so is there some reason we
can't shove this into there? Less code for things that aren't relevant I
guess?
As mentioned earlier, the register layout is not compatible and some
other differences w.r.t to code like headrooms, using mfd driver to
register ldos etc..
