12description: |
13  Hisilicon designs some special domain controllers for mobile platform,
14  such as: the power Always On domain controller, the Media domain
15  controller(e.g. codec, G3D ...) and the Power Management domain
16  controller.
17
18  The compatible names of each domain controller are as follows:
19  Power Always ON domain controller  --> hisilicon,hi6220-aoctrl
20  Media domain controller            --> hisilicon,hi6220-mediactrl
21  Power Management domain controller --> hisilicon,hi6220-pmctrl
