Subject: [PATCH 07/10] dt-bindings: remoteproc: qcom,wcnss: Deprecate regulators for PDs
Date: Wed, 16 Sep 2020 12:41:32 +0200 [thread overview]
Message-ID: <20200916104135.25085-8-stephan@gerhold.net> (raw)
In-Reply-To: <20200916104135.25085-1-stephan@gerhold.net>
So far we have been doing all proxy votes by voting for raw voltages/load
through the regulator interface. But actually VDDCX and VDDMX represent
power domains that should be preferably managed using corner votes
through the power domain interface.
Document that those should be specified as power domains for
qcom,pronto-v1/2-pil and deprecate using them through the regulator
interface.
