Subject: usb: host: tegra: Locate a PHY via standard API
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7db71a9a6707284f3d9075fff2ad674f6a51c359;p=linux-beck.git

usb: host: tegra: Locate a PHY via standard API

Use devm_get_phy_by_phandle to get a PHY device instead of the custom
Tegra functions.
