  • Samsung Exynos Power Domains

Exynos processors include support for multiple power domains which are used
to gate power to one or more peripherals on the processor.

Required Properties:

  • compatible: should be one of the following.
    • samsung,exynos4210-pd - for exynos4210 type power domain.
  • reg: physical base address of the controller and length of memory mapped
    region.

Node of a device using power domains must have a samsung,power-domain property
defined with a phandle to respective power domain.

Example:

lcd0: power-domain-lcd0 {
    compatible = "samsung,exynos4210-pd";
    reg = <0x10023C00 0x10>;
};

Example of the node using power domain:

node {
    /* ... */
    samsung,power-domain = <&lcd0>;
    /* ... */
};
