Subject: [PATCH v7 2/8] Revert "clk: qcom: gcc-sc7280: use new clk_regmap_mux_safe_ops for PCIe pipe clocks"
Date: Sat, 21 May 2022 03:53:37 +0300 [thread overview]
Message-ID: <20220521005343.1429642-3-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220521005343.1429642-1-dmitry.baryshkov@linaro.org>
Johan Hovold has pointed out that there are several deficiencies and a
race condition in the regmap_mux_safe ops that were merged. Revert the
commit that switches gcc-sc7280 driver to use regmap_mux_safe.
