Subject: [PATCH V7 2/5] clk: qcom: lpass: Handle the regmap overlap of lpasscc and lpass_aon
Date: Wed, 27 Jul 2022 13:57:54 +0530 [thread overview]
Message-ID: <1658910477-6494-3-git-send-email-quic_c_skakit@quicinc.com> (raw)
In-Reply-To: <1658910477-6494-1-git-send-email-quic_c_skakit@quicinc.com>
Move registration of lpass_q6ss_ahbm_clk and lpass_q6ss_ahbs_clk to
lpass_aon_cc_sc7280_probe and register them only if "qcom,adsp-pil-mode"
is enabled in the lpass_aon DT node.
