+Common Domains Controller bindings properties
+
+Domains Controller framework defines common bindings properties to describe
+the configurations to be applied for each device.
+
+Domains Controller bindings:
+- #domainctrl-cells : provide the number of parameters provided with the
+ phandle by the client device
+
+Client device node bindings:
+- domainsctrl-names : list of strings to name the configurations.
+ "default" and "unbind" are reserved names used by
+ the framework.
+- domainsctrl-X : list of configurations to be applied where X
is
+ the index of the configuration within the node.
+
+Example of usage with:
+- a domains controller with a 2 parameters cell
+- a domains controller with a 3 parameters cell
+- a client device node using the both controllers and 2 configurations
+ named "default" and "unbind"
+
+ctrl0: ctrl@0 {
+ #domainctrl-cells = <2>;
+};
+
+ctrl1: ctrl@1 {
+ #domainctrl-cells = <3>;
+};
+
+foo@0 {
+ domains-names = "default", "unbind";
+ domainctrl-0 = <&ctrl0 1 2>, <&ctrl1 3 4 5>;
+ domainctrl-1 = <&ctrl0 6 7>, <&ctrl1 8 9 0>;
+};
