| The global utilities block controls PCIE device enabling, alternate |
| function selection for multiplexed signals, consistency of HDA, USB |
| and PCIE, configuration of memory controller, rtc controller, lio |
| controller, and clock control. This patch adds a driver to manage |
| and access global utilities block for LoongArch architecture Loongson-2 |
| SoCs. Initially only reading SVR and registering soc device are |
| supported. Other guts accesses, such as reading firmware configuration |
| by default, should eventually be added into this driver as well. |

| The Loongson-2's power management controller was ACPI, supports ACPI |
| S2Idle (Suspend To Idle), ACPI S3 (Suspend To RAM), ACPI S4 (Suspend To |
| Disk), ACPI S5 (Soft Shutdown) and supports multiple wake-up methods |
| (USB, GMAC, PWRBTN, etc.). This driver was to add power management |
| controller support that base on dts for Loongson-2 series SoCs. |
