-Binding for Keystone gate control driver which uses PSC controller IP.
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : shall be "ti,keystone,psc-clock".
-- #clock-cells : from common clock binding; shall be set to 0.
-- clocks : parent clock phandle
-- reg :	psc control and domain address address space
-- reg-names : psc control and domain registers
-- domain-id : psc domain id needed to check the transition state register
-
-Optional properties:
-- clock-output-names : From common clock binding to override the
-			default output clock name
-Example:
-	clkusb: clkusb {
-		#clock-cells = <0>;
-		compatible = "ti,keystone,psc-clock";
-		clocks = <&chipclk16>;
-		clock-output-names = "usb";
-		reg = <0x02350008 0xb00>, <0x02350000 0x400>;
-		reg-names = "control", "domain";
-		domain-id = <0>;
