| 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. |
