+Mediatek MT7530 Ethernet switch
+================================
+
+Required properties:
+
+- compatible: Must be compatible = "mediatek,mt7530";
+- #address-cells: Must be 1
+- #size-cells: Must be 0
+- mediatek,ethsys: Phandle to the syscon node that handles the reset.
+- mediatek,ethernet: Phandle to the syscon node that Mediatek ethernet driver
+	provides that handles the TRGMII setup used by the switch.
+	See
+	Documentation/devicetree/bindings/net/mediatek-net.txt for the detailed
+	setup on mediatek ethernet.
+- mediatek,mcm: String, should be "enabled" or "disabled" to indicate that
+	either MT7530 is the part on multi-chip module belong to MT7623A has
+	or the remotely standalone chip as the function MT7623N reference board
+	provided for.
+- core-supply: Phandle to the regulator node necessary for the core power.
+- io-supply: Phandle to the regulator node necessary for the I/O power
+	See Documentation/devicetree/bindings/regulator/mt6323-regulator.txt
+	for details for the regulator setup on these boards.
+- mediatek,reset-pin: Phandle to the pinctrl node used for the reset. Which
+	must be required if the property mediatek,mcm of specified as
+	"disabled". See
+	Documentation/devicetree/bindings/pinctrl/pinctrl-mt65xx.txt for
+	the mediatek pintcrl setting for the details.
+
+Each port children node within ports container must have the following
+mandatory properties:
+- reg			: Port address described must be 6 for CPU port
+			and from 0 to 5 for user ports.
+
+See Documentation/devicetree/bindings/dsa/dsa.txt for a list of additional
+required, optional properties and how the integrated switch subnodes must
+be specified.
+
+Example:
+
+	&mdio0 {
+		switch@0 {
+			compatible = "mediatek,mt7530";
+			#address-cells = <1>;
+			#size-cells = <0>;

Use the reset binding?

What's wrong with the normal pinctrl binding?
