7 title: Hisilicon system controller
10   - Wei Xu <xuwei5@hisilicon.com>
13   The Hisilicon system controller is used on many Hisilicon boards, it can be
14   used to assist the slave core startup, reboot the system, etc.
16   There are some variants of the Hisilicon system controller, such as HiP01,
17   Hi3519, Hi6220 system controller, each of them is mostly compatible with the
18   Hisilicon system controller, but some same registers located at different
19   offset. In addition, the HiP01 system controller has some specific control
22   The compatible names of each system controller are as follows:
23   Hisilicon system controller   --> hisilicon,sysctrl
24   HiP01     system controller   --> hisilicon,hip01-sysctrl
25   Hi6220    system controller   --> hisilicon,hi6220-sysctrl
26   Hi3519    system controller   --> hisilicon,hi3519-sysctrl
