This is an example implementation of power management using C907 IPMC, which mainly implements sbi_hsm_device, sbi_system_reset_device and sbi_system_suspend_device defined by opensbi.

DTS example:

{
	model = "xuantie,dummy";
	compatible = "xuantie,dummy";

	ipmc: xuantie_ipmc@26900000 {
		compatible = "xuantie,ipmc";
		reg = <0x00000000 0x26900000 0x00000000 0x00001000>;
	};
}
