+
+description: |
+ The i.MX7S/D General Power Control (GPC) block contains Power Gating
+ Control (PGC) for various power domains.
+
+ Power domains contained within GPC node are generic power domain
+ providers, documented in
+ Documentation/devicetree/bindings/power/power-domain.yaml, which are
+ described as subnodes of the power gating controller 'pgc' node.
+
+ IP cores belonging to a power domain should contain a 'power-domains'
+ property that is a phandle for PGC node representing the domain.
