7 title: Mediatek Power Domains Controller
14   Mediatek processors include support for multiple power domains which can be
15   powered up/down by software based on different application scenes to save power.
17   IP cores belonging to a power domain should contain a 'power-domains'
22     pattern: '^power-controller(@[0-9a-f]+)?$'
