In case of a on-board autonomous hub between the phy and the connectors, so no driver to drive it nor to get the vbus-supply property to provide VBUS to the hub, then the connectors, how to use connector ?

This patch adds vbus-supply optional property to phy sub-nodes. A regulator for USB VBUS may be needed for host mode. Signed-off-by: Amelie Delaunay <amelie.delaunay@foss.st.com> --- Documentation/devicetree/bindings/phy/phy-stm32-usbphyc.yaml | 3 +++ 1 file changed, 3 insertions(+)
