Below is the equation in original code:

tps65217_uv1_ranges:
        0  ... 24: uV = vsel * 25000 + 900000;
        25 ... 52: uV = (vsel - 24) * 50000 + 1500000;
                      = (vsel - 25) * 50000 + 1550000;
        53 ... 55: uV = (vsel - 52) * 100000 + 2900000;
                      = (vsel - 53) * 100000 + 3000000;
        56 ... 62: uV = 3300000;

tps65217_uv2_ranges:
        0  ...  8: uV = vsel * 50000 + 1500000;
        9  ... 13: uV = (vsel - 8) * 100000 + 1900000;
                      = (vsel - 9) * 100000 + 2000000;
        14 ... 31: uV = (vsel - 13) * 50000 + 2400000;
                      = (vsel - 14) * 50000 + 2450000;

The voltage tables are composed of linear ranges.
This patch converts this driver to use multiple linear ranges APIs.

In original code, voltage range for DCDC1 is 900000 ~ 1800000 and voltage range
for DCDC3 is 900000 ~ 1500000.  This patch separates the range 25~52 in
tps65217_uv1_ranges table to two linear ranges: 25~30 and 31~52.
This change makes it possible to reuse the same linear_ranges table for DCDCx.

The driver adds support for the following DA9063 PMIC regulators:
 - 11x LDOs (named LDO1 - LDO11),
 - 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI),

Regulators provide following operations:
 - REGULATOR_CHANGE_STATUS and REGULATOR_CHANGE_VOLTAGE for all regulators,
 - REGULATOR_CHANGE_MODE for LDOs and buck converters, where:
     - LDOs allow REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY,
     - buck converters allow REGULATOR_MODE_FAST, REGULATOR_MODE_NORMAL
       and REGULATOR_MODE_STANDBY,
 - REGULATOR_CHANGE_CURRENT for buck converters (current limits).

The driver generates REGULATOR_EVENT_OVER_CURRENT for LDO3, LDO4, LDO7, LDO8
and LDO11.

Internally, PMIC provides two voltage configurations for normal and suspend
system state for each regulator. The driver switches between those on
suspend/wake-up to provide quick and fluent output voltage change.

This driver requires MFD core driver for operation.

That was how it was designed and all the callers expect it.
