+description: |
+  A simple bus enabling access to shared peripherals.
+
+  The "spba-bus" follows the "simple-bus" set of properties, as
+  specified in the Devicetree Specification.  It is an extension of
+  "simple-bus" because the SDMA controller uses this compatible flag to
+  determine which peripherals are available to it and the range over which
+  the SDMA can access.  There are no special clocks for the bus, because
+  the SDMA controller itself has its interrupt, and clock assignments.
+
+properties:
+  $nodename:
+    pattern: "^bus(@[0-9a-f]+)?$"
+
+  compatible:
+    contains:
+      const: fsl,spba-bus
+    description:
+      Shall contain "fsl,spba-bus" in addition to "simple-bus"
+      compatible strings.
+
+  '#address-cells':
+    enum: [ 1, 2 ]
+
+  '#size-cells':
+    enum: [ 1, 2 ]
+
+  ranges: true
+
+required:
+  - compatible
+  - '#address-cells'
+  - '#size-cells'
+  - ranges
+
+additionalProperties: true
+
+examples:
+  - |
+    bus {
+        compatible = "fsl,spba-bus", "simple-bus";
+        #address-cells = <1>;
+        #size-cells = <1>;
+        ranges;
+    };
