Subject: [PATCH V9 2/5] clk: qcom: lpass: Handle the regmap overlap of lpasscc and lpass_aon
Date:   Thu, 1 Sep 2022 09:47:23 +0530

From: Taniya Das <quic_tdas@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.
