[PATCH] regulator: Change regulator-coupled-max-spread property

From: Dmitry Osipenko
Date: Sun Nov 18 2018 - 16:56:16 EST


Redefine binding for regulator-coupled-max-spread property in a way that
max-spread values are defined per regulator couple instead of defining
single max-spread for the whole group of coupled regulators.

With that change the following regulators coupling configuration will be
possible:

regA: regulatorA {
regulator-coupled-with = <&regB &regC>;
regulator-coupled-max-spread = <100000 300000>;
};

regB: regulatorB {
regulator-coupled-with = <&regA &regC>;
regulator-coupled-max-spread = <100000 200000>;
};

regC: regulatorC {
regulator-coupled-with = <&regA &regB>;
regulator-coupled-max-spread = <300000 200000>;
};

Note that the regulator-coupled-max-spread property does not have any
users yet, hence it's okay to change the binding.
