    Usage: required
    Value type: <prop-encoded-array>
    Definition: Should contain clock specifier for phy, calibration and
                a calibration sleep clock

- clock-names:
    Usage: required
    Value type: <stringlist>
    Definition: Should contain "phy, "cal" and "cal_sleep"

- pinctrl-names:
    Usage: required
    Value type: <stringlist>
    Definition: Should contain "init" and "default" in that order

- pinctrl-0:
    Usage: required
    Value type: <prop-encoded-array>
    Definition: List of pinctrl settings to apply to keep HSIC pins in a glitch
                free state

- pinctrl-1:
    Usage: required
    Value type: <prop-encoded-array>
    Definition: List of pinctrl settings to apply to mux out the HSIC pins
