    1 * ST-Ericsson UX500 PM Domains
    2 
    3 UX500 supports multiple PM domains which are used to gate power to one or
    4 more peripherals on the SOC.
    5 
    6 The implementation of PM domains for UX500 are based upon the generic PM domain
    7 and use the corresponding DT bindings.
    8 
    9 ==PM domain providers==
   10 
   11 Required properties:
   12  - compatible: Must be "stericsson,ux500-pm-domains".
   13  - #power-domain-cells : Number of cells in a power domain specifier, must be 1.
   14 
   15 Example:
   16         pm_domains: pm_domains0 {
   17                 compatible = "stericsson,ux500-pm-domains";
   18                 #power-domain-cells = <1>;
   19         };
   20 
   21 ==PM domain consumers==
   22 
   23 Required properties:
   24  - power-domains: A phandle and PM domain specifier. Below are the list of
   25                 valid specifiers:
   26 
   27                 Index   Specifier
   28                 -----   ---------
   29                 0       DOMAIN_VAPE
   30 
   31 Example:
   32         sdi0_per1@80126000 {
   33                 compatible = "arm,pl18x", "arm,primecell";
   34                 power-domains = <&pm_domains DOMAIN_VAPE>
   35         };
