regulator: Change regulator-coupled-max-spread property
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>; }; Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
