+Status: Unstable - ABI compatibility may be broken in the future
+
+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>;
+       };
