Add a device tree binding for the PHY. Signed-off-by: Icenowy Zheng Reviewed-by: Chen-Yu Tsai --- Changes in v3: - Added Chen-Yu's Review tag. Rob, Although you mentioned that the supply is for the port, not the phy; currently in USB situation "powering on the PHY" also indicates "powering on the port" and nearly all usages of phy-supply is for Vbus. Maybe we should change the overall phy-supply to satisfy this.
