* ST-Ericsson UX500 PM Domains
UX500 supports multiple PM domains which are used to gate power to one or
more peripherals on the SOC.
The implementation of PM domains for UX500 are based upon the generic PM domain
and use the corresponding DT bindings.
==PM domain providers==
Required properties:
- compatible: Must be "stericsson,ux500-pm-domains".
- #power-domain-cells : Number of cells in a power domain specifier, must be 1.
Example:
pm_domains: pm_domains0 {
compatible = "stericsson,ux500-pm-domains";
#power-domain-cells = <1>;
};
==PM domain consumers==
Required properties:
- power-domains: A phandle and PM domain specifier. Below are the list of
valid specifiers:
Index Specifier
----- ---------
0 DOMAIN_VAPE
Example:
sdi0_per1@80126000 {
compatible = "arm,pl18x", "arm,primecell";
power-domains = <&pm_domains DOMAIN_VAPE>
};
