比如,dsp子系统power domain下面,有多个dsp核,每个dsp核对应一个power domain。这样,每个dsp核设备驱动都要关联到对应的dsp核power domain上,通过dsp核设备的dts里power-domains的属性引用(power domain framework的节点引用及具体power domain的编号),将dsp核设备与相应的power domain关联起来; 使用power domain的框架:...

[17]. In the meantime, DT has also been used to solve problems arising in modern power systems. For example, the work [18] proposes a DT framework in smart grids to assess the remaining useful life of equipment. The successful application of DT in various domains also underscores their ...
Power Domains/Rails Mapping: A direct consequence of this behavior distinction is the need to map and control additional power domains and rails, such as those for internal SoC devices. This ensures precise control over which parts of the system are powered during suspend or turn-off states. ...
