+title: Apple SoC Power Manager (PMGR)
+
+maintainers:
+ - Hector Martin <marcan@marcan.st>
+
+description: |
+ Apple SoCs include PMGR blocks responsible for power management,
+ which can control various clocks, resets, power states, and
+ performance features. This node represents the PMGR as a syscon,
+ with sub-nodes representing individual features.
