+title: IBM On-Chip Controller (OCC) accessed from a service processor
+
+maintainers:
+  - Eddie James <eajames@...ux.ibm.com>
+
+description: |
+  The POWER processor On-Chip Controller (OCC) helps manage power and
+  thermals for the system. A service processor or baseboard management
+  controller can query the OCC for it's power and thermal data to report
+  through hwmon.
+
+properties:
+  compatible:
+    enum:
+      - ibm,p9-occ-hwmon
+      - ibm,p10-occ-hwmon
+
+  ibm,no-poll-on-init:
+    description: This property describes whether or not the OCC should
+      be polled during driver initialization.
+    type: boolean
+
+required:
+  - compatible
+
+additionalProperties: false
+
+examples:
+  - |
+    hwmon {
+        compatible = "ibm,p10-occ-hwmon";
+        ibm,no-poll-on-init;
