[PATCH v4 2/9] staging: dwc2: update DT binding to add generic clock/phy properties

[Matt Porter]

dwc2/s3c-hsotg require a single clock to be specified and optionally
a generic phy. On the s3c-hsotg driver old style USB phy support is
present as a fallback so the generic phy properties are optional.
