Subject: [PATCH] phy: qualcomm: phy-qcom-qmp: add support for combo USB3+DP phy on SDM845
Date:   Tue,  9 Aug 2022 22:09:26 -0500

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

Define configuration to be used by combo USB3 + DisplayPort phy on
SDM845 SoC family. It closely follows sc7180, however like the main USB3
phy it uses the qmp_v3_usb3phy_cfg config.
