Subject: [PATCH v11 3/5] clk: qcom: gcc-sc7280: use new clk_regmap_phy_mux_ops for PCIe pipe clocks
Date: Wed,  8 Jun 2022 13:52:36 +0300	[thread overview]
Message-ID: <20220608105238.2973600-4-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220608105238.2973600-1-dmitry.baryshkov@linaro.org>

Use newly defined clk_regmap_phy_mux_ops for PCIe pipe clocks to let
the clock framework automatically park the clock when the clock is
switched off and restore the parent when the clock is switched on.
