2*4882a593Smuzhiyun
3*4882a593SmuzhiyunUX500 supports multiple PM domains which are used to gate power to one or
4*4882a593Smuzhiyunmore peripherals on the SOC.
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunThe implementation of PM domains for UX500 are based upon the generic PM domain
7*4882a593Smuzhiyunand use the corresponding DT bindings.
