Subject: [PATCH v3 02/16] phy: qcom-qmp-usb: simplify clock handling
Date: Fri, 25 Aug 2023 00:19:38 +0300 [thread overview]
Message-ID: <20230824211952.1397699-3-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20230824211952.1397699-1-dmitry.baryshkov@linaro.org>
For the existing PHYs for new binding we are going to drop ref_clk_src
clock and always use ref clock. Rather than introducing additional code
to handle legacy vs current bindings (and clock names), use
devm_clk_bulk_get_optional() when new bindings are used and
devm_clk_bulk_get_all() when legacy bindings are in place.
