Qualcomm platforms have LAB(LCD AMOLED Boost)/IBB(Inverting Buck Boost) regulators, labibb for short, which are used as power supply for LCD Mode displays. This patch adds labibb regulator driver for pmi8998 PMIC, found on SDM845 platforms.

This patch adds support for ON Semiconductor FAN53880 regulator. The FAN53880 is an I2C porgrammable power management IC (PMIC) that contains a BUCK (step-down converter), four LDOs (low dropouts) and one BOOST (step-up converter). It is designed for mobile power applications.

lib: Add linear ranges helper library and start using it Series extracts a "linear ranges" helper out of the regulator framework. Linear ranges helper is intended to help converting real-world values to register values when conversion is linear. I suspect this is useful also for power subsystem and possibly for clk.
