Some PHYs (for example Exynos5 USB3.0 DRD PHY) require calibration to be

This property isn't needed and not yet used anywhere. The swap-dx-lanes

calibration code when phy_calibrate() is called for USB3.0 (PIPE3) PHY.

Samsung PHY drivers control the power to the SoC core components needed by
their client devices (USB HCDs, SATA, camera ISP bridge, DP encoder) to
properly operate. Disabling PHYs in runtime usually causes the client
device to crash with external abort exception or similar issue due to lack
of API
