Hisilicon HiP05 PERISUB system controller
Required properties:
- compatible : "hisilicon,hip05-perisubc", "syscon";
- reg : Register address and size
The HiP05 PERISUB system controller is shared by peripheral controllers in
HiP05 Soc to implement some basic configurations. The peripheral
controllers include mdio, ddr, iic, uart, timer and so on.
Example:
/* for HiP05 perisub-ctrl-c system */
peri_c_subctrl: syscon@80000000 {
compatible = "hisilicon,hip05-perisubc", "syscon";
reg = <0x0 0x80000000 0x0 0x10000>;
