PM / Domains: dt: Add a power-domain-names property (79a5c451) · Commits · 戴 / test

Let's add a power-domain-names property, to allow consumer drivers to match the power-domains specifiers via a list of power domain names. This follows the same concept as for other similar DT bindings. Signed-off-by:

		Example:
