c488f0071e regulator: qcom_smd: Fix voltage ranges for pma8084 ftsmps and pldo
The voltage ranges listed here are wrong. The pma8084 pldo
supports three different overlapping voltage ranges with
differing step sizes and the pma8084 ftsmps supports two. These
ranges can be seen in the "native" spmi regulator driver
(qcom_spmi-regulator.c) at pldo_ranges[] and ftsmps_ranges[]
respectively. Port these ranges over to the RPM SMD regulator
driver so that we list the appropriate set of supported voltages
on these types of regulators.

290284776b regulator: qcom_smd: Fix voltage ranges for pm8x41
The voltage ranges listed here are wrong. The correct ranges can
be seen in the "native" spmi regulator driver
qcom_spmi-regulator.c at pldo_ranges[], ftsmps_ranges[] and
boost_ranges[] for the pldo, ftsmps, and boost type regulators.
Port these ranges over to the RPM SMD regulator driver so that we
list the appropriate set of supported voltages on pldos.

Doing this allows us to specify a voltage like 3075000 for l24,
whereas before that wasn't a supported voltage.

b7a8524cfa regulator: qcom_smd: Avoid overlapping linear voltage ranges
The pm8x41_hfsmps ranges overlap. The first range is from 375000
to 1562500:

 375000 + (95 * 12500) == 1562500

and the second range starts at 1550000. Interestingly, the second
range ends at the correct value when it's set to be the
appropriate start value, 1575000:

 1575000 + ((158 - 96) * 25000) == 3125000

43160ffd12 regulator: qcom_smd: Remove list_voltage callback for rpm_smps_ldo_ops_fixed
Use regulator_list_voltage_linear_range in rpm_smps_ldo_ops_fixed is
wrong because it is used for fixed regulator without any linear range.
The rpm_smps_ldo_ops_fixed is used for pm8941_lnldo which has fixed_uV
set and n_voltages = 1. In this case, regulator_list_voltage() can return
rdev->desc->fixed_uV without .list_voltage implementation.

3bfbb4d1a4 regulator: qcom_smd: add list_voltage callback
This patch adds support to list_voltage callback, so that consumers
like mmc core, can get information of supported voltage range.

Without this patch there is no way for mmc core to know this voltage range.

d1e44b6b28 regulator: qcom_smd: add regulator ops for pm8941 lnldo
After "regulator: qcom_smd: add list_voltage callback" patch adding
pm8941 lnldo regulators would bug on list_voltages as it is a fixed
regulator without any linear range.
This patch fixes that issue by adding dedicated ops for pm8941 lnldo
without list_voltages callback.

Just setting fixed_uV is not enough, the regulator core will also check
n_voltages setting. The fixed_uV only works when n_voltages is 1.
