Subject: [PATCH v2] dt-bindings: regulator: Change regulator-coupled-max-spread property
Date: Mon, 19 Nov 2018 00:56:16 +0300 [thread overview]
Message-ID: <20181118215619.21518-2-digetx@gmail.com> (raw)
In-Reply-To: <20181118215619.21518-1-digetx@gmail.com>
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.

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.
