+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.
+

+ compatible:
+ enum:
+ - actions,s500-sps
