Subject: [PATCH v6 5/5] PCI: qcom-ep: Setup PHY to work in EP mode
Date: Tue, 27 Sep 2022 12:22:06 +0300 [thread overview]
Message-ID: <20220927092207.161501-6-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220927092207.161501-1-dmitry.baryshkov@linaro.org>
Call phy_set_mode_ext() to notify the PHY driver that the PHY is being
used in the EP mode.
