Subject: [PATCH v5 5/5] pinctrl: qcom: Update clock voting as optional
Date: Tue, 7 Dec 2021 21:05:39 +0530 [thread overview]
Message-ID: <1638891339-21806-6-git-send-email-quic_srivasam@quicinc.com> (raw)
In-Reply-To: <1638891339-21806-1-git-send-email-quic_srivasam@quicinc.com>
Update bulk clock voting to optional voting as ADSP bypass platform doesn't
need macro and decodec clocks, these are maintained as power domains and
operated from lpass audio core cc.
