+description: |
+  Actions Semi Owl SoCs feature a Smart Power System (SPS) that manages power
+  domains to optimize power usage across various hardware blocks. Each power
+  domain corresponds to a specific hardware block and is represented by a bit
+  in the power control register and an acknowledgment bit, which is then
+  translated into a corresponding voltage on a rail.
+
+properties:
+  compatible:
+    enum:
+      - actions,s500-sps
+      - actions,s700-sps
+      - actions,s900-sps

+  reg:
+    maxItems: 1
