regulator: pm8018-regulator: Add regulator driver for PM8018
Create a regulator driver to control all regulators on the Qualcomm
PM8018 PMIC chip. This chip contains several different types of
regulators with a wide range of abilities and voltage ranges.
Five different regulator types are available on the PM8018.
PLDO - PMOS low drop out linear regulator
NLDO - NMOS low drop out linear regulator
NLDO1200 - 1.2A NMOS LDO (different control structure than other LDOs)
SMPS - switched-mode power supply
VS - voltage switch
The driver interfaces with the PMIC using Qualcomm's SSBI bus.
Calls to this bus are abstracted through the pm8xxx_readb/writeb API.
