Subject: [PATCH v2 2/5] clk: qcom: gcc-sm8450: use new clk_regmap_mux_safe_ops for PCIe pipe clocks
Date: Tue, 12 Apr 2022 22:38:36 +0300	[thread overview]
Message-ID: <20220412193839.2545814-3-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220412193839.2545814-1-dmitry.baryshkov@linaro.org>

Use newly defined clk_regmap_mux_safe_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.
