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";
HiP01 ca9x2 Board
Required root node properties:
- compatible = "hisilicon,hip01-ca9x2";
HiKey Board
Required root node properties:
- compatible = "hisilicon,hikey";
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;
cpu 3, reg + 0x8;
If reg value is not zero, cpun exit wfi and go
- resume-offset : offset in sysctrl for notifying cpu0 when resume
- reboot-offset : offset in sysctrl for system reboot
Example:
/* for Hi3620 */
sysctrl: system-controller@fc802000 {
compatible = "hisilicon,sysctrl";
reg = <0xfc802000 0x1000>;
smp-offset = <0x31c>;
resume-offset = <0x308>;
reboot-offset = <0x4>;
};
-----------------------------------------------------------------------
Hisilicon HiP01 system controller
Required properties:
- compatible : "hisilicon,hip01-sysctrl"
- reg : Register address and size
The HiP01 system controller is mostly compatible with hisilicon
system controller,but it has some specific control registers for
HIP01 SoC family, such as slave core boot, and also some same
registers located at different offset.
Example:
/* for hip01-ca9x2 */
sysctrl: system-controller@10000000 {
compatible = "hisilicon,hip01-sysctrl", "hisilicon,sysctrl";
reg = <0x10000000 0x1000>;
reboot-offset = <0x4>;
};
-----------------------------------------------------------------------
Hisilicon CPU controller
Required properties:
- compatible : "hisilicon,cpuctrl"
- reg : Register address and size

in CPU controller, especially in HIX5HD2 SoC.
-----------------------------------------------------------------------
PCTRL: Peripheral misc control register
Required Properties:
- compatible: "hisilicon,pctrl"
- reg: Address and size of pctrl.
Example:
/* for Hi3620 */
