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 = <®B ®C>; regulator-coupled-max-spread = <100000 300000>; }; regB: regulatorB { regulator-coupled-with = <®A ®C>; regulator-coupled-max-spread = <100000 200000>; }; regC: regulatorC { regulator-coupled-with = <®A ®B>; 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. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> --- v2: Added note to the commit description, saying that the property doesn't have users yet. That was requested by Rob Herring in the review comment to v1. Documentation/devicetree/bindings/regulator/regulator.txt | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
