Merge tag 'linear-ranges-lib' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator into regulator-5.8
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.
