+description: |
+ The Hisilicon system controller is used on many Hisilicon boards, it can be
+ used to assist the slave core startup, reboot the system, etc.
+
+ There are some variants of the Hisilicon system controller, such as HiP01,
+ Hi3519, Hi6220 system controller, each of them is mostly compatible with the
+ Hisilicon system controller, but some same registers located at different
+ offset. In addition, the HiP01 system controller has some specific control
+ registers for HIP01 SoC family, such as slave core boot.
+
+ The compatible names of each system controller are as follows:
+ Hisilicon system controller --> hisilicon,sysctrl
+ HiP01 system controller --> hisilicon,hip01-sysctrl
+ Hi6220 system controller --> hisilicon,hi6220-sysctrl
+ Hi3519 system controller --> hisilicon,hi3519-sysctrl
