- Hisilicon Platforms Device Tree Bindings
- ----------------------------------------------------
- Hi4511 Board
- Required root node properties:
- - compatible = "hisilicon,hi3620-hi4511";
- HiP04 D01 Board
- Required root node properties:
- - compatible = "hisilicon,hip04-d01";
- Hisilicon system controller
- Required properties:
- - compatible : "hisilicon,sysctrl"
- - reg : Register address and size
- Optional properties:
- - smp-offset : offset in sysctrl for notifying slave cpu booting
- cpu 1, reg;
- cpu 2, reg + 0x4;
