dt-bindings: net: phy: vsc8531: document the load/save GPIO
A new optional property can be used to reference the load/save GPIO, used for PTP hardware clock (PHC) operations. This patch documents it in the binding documentation. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
