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

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