Documentation: dt-bindings: Add snps,need-phy-for-wake for dwc2 USB
Some SoCs with a dwc2 USB controller may need to keep the PHY on to support remote wakeup. Allow specifying this as a device tree property. Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
